+
+Native Wayland color picker with magnifier, no external dependencies. Supports HiDPI and fractional scaling.
+
+```bash
+dms color pick              # Pick color, output hex
+dms color pick --rgb        # Output as RGB (255 128 64)
+dms color pick --hsv        # Output as HSV (24 75% 100%)
+dms color pick --json       # Output all formats as JSON
+dms color pick -a           # Auto-copy to clipboard
+```
+
+The on-screen preview displays the selected format. JSON output includes hex, RGB, HSL, HSV, and CMYK values.

+// This interface works with two concepts: the source rectangle (src_x,
+// src_y, src_width, src_height), and the destination size (dst_width,
+// dst_height). The contents of the source rectangle are scaled to the
+// destination size, and content outside the source rectangle is ignored.
+// This state is double-buffered, see wl_surface.commit.
+//
+// The two parts of crop and scale state are independent: the source
+// rectangle, and the destination size. Initially both are unset, that
+// is, no scaling is applied. The whole of the current wl_buffer is
+// used as the source, and the surface size is as defined in
+// wl_surface.attach.
+//
+// If the destination size is set, it causes the surface size to become
+// dst_width, dst_height. The source (rectangle) is scaled to exactly
+// this size. This overrides whatever the attached wl_buffer size is,
+// unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
+// has no content and therefore no size. Otherwise, the size is always
+// at least 1x1 in surface local coordinates.
+//
+// If the source rectangle is set, it defines what area of the wl_buffer is
+// taken as the source. If the source rectangle is set and the destination
+// size is not set, then src_width and src_height must be integers, and the
+// surface size becomes the source rectangle size. This results in cropping
+// without scaling. If src_width or src_height are not integers and
+// destination size is not set, the bad_size protocol error is raised when
+// the surface state is applied.
+//
+// The coordinate transformations from buffer pixel coordinates up to
+// the surface-local coordinates happen in the following order:
+// 1. buffer_transform (wl_surface.set_buffer_transform)
+// 2. buffer_scale (wl_surface.set_buffer_scale)
+// 3. crop and scale (wp_viewport.set*)
+// This means, that the source rectangle coordinates of crop and scale
+// are given in the coordinates after the buffer transform and scale,
+// i.e. in the coordinates that would be the surface-local coordinates
+// if the crop and scale was not applied.
+//
+// If src_x or src_y are negative, the bad_value protocol error is raised.
+// Otherwise, if the source rectangle is partially or completely outside of
+// the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
+// when the surface state is applied. A NULL wl_buffer does not raise the
+// out_of_buffer error.
+//
+// If the wl_surface associated with the wp_viewport is destroyed,
+// all wp_viewport requests except 'destroy' raise the protocol error
+// no_surface.

+// The two parts of crop and scale state are independent: the source
+// rectangle, and the destination size. Initially both are unset, that
+// is, no scaling is applied. The whole of the current wl_buffer is
+// used as the source, and the surface size is as defined in
+// wl_surface.attach.
+//
+// If the destination size is set, it causes the surface size to become
+// dst_width, dst_height. The source (rectangle) is scaled to exactly
+// this size. This overrides whatever the attached wl_buffer size is,
+// unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
+// has no content and therefore no size. Otherwise, the size is always
+// at least 1x1 in surface local coordinates.
+//
+// If the source rectangle is set, it defines what area of the wl_buffer is
+// taken as the source. If the source rectangle is set and the destination
+// size is not set, then src_width and src_height must be integers, and the
+// surface size becomes the source rectangle size. This results in cropping
+// without scaling. If src_width or src_height are not integers and
+// destination size is not set, the bad_size protocol error is raised when
+// the surface state is applied.
+//
+// The coordinate transformations from buffer pixel coordinates up to
+// the surface-local coordinates happen in the following order:
+// 1. buffer_transform (wl_surface.set_buffer_transform)
+// 2. buffer_scale (wl_surface.set_buffer_scale)
+// 3. crop and scale (wp_viewport.set*)
+// This means, that the source rectangle coordinates of crop and scale
+// are given in the coordinates after the buffer transform and scale,
+// i.e. in the coordinates that would be the surface-local coordinates
+// if the crop and scale was not applied.
+//
+// If src_x or src_y are negative, the bad_value protocol error is raised.
+// Otherwise, if the source rectangle is partially or completely outside of
+// the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
+// when the surface state is applied. A NULL wl_buffer does not raise the
+// out_of_buffer error.
+//
+// If the wl_surface associated with the wp_viewport is destroyed,
+// all wp_viewport requests except 'destroy' raise the protocol error
+// no_surface.

+      A keyboard shortcuts inhibitor instructs the compositor to ignore
+      its own keyboard shortcuts when the associated surface has keyboard
+      focus. As a result, when the surface has keyboard focus on the given
+      seat, it will receive all key events originating from the specified
+      seat, even those which would normally be caught by the compositor for
+      its own shortcuts.
+
+      The Wayland compositor is however under no obligation to disable
+      all of its shortcuts, and may keep some special key combo for its own
+      use, including but not limited to one allowing the user to forcibly
+      restore normal keyboard events routing in the case of an unwilling
+      client. The compositor may also use the same key combo to reactivate
+      an existing shortcut inhibitor that was previously deactivated on
+      user request.
+
+      When the compositor restores its own keyboard shortcuts, an
+      "inactive" event is emitted to notify the client that the keyboard
+      shortcuts inhibitor is not effectively active for the surface and
+      seat any more, and the client should not expect to receive all
+      keyboard events.
+
+      When the keyboard shortcuts inhibitor is inactive, the client has
+      no way to forcibly reactivate the keyboard shortcuts inhibitor.
+
+      The user can chose to re-enable a previously deactivated keyboard
+      shortcuts inhibitor using any mechanism the compositor may offer,
+      in which case the compositor will send an "active" event to notify
+      the client.
+
+      If the surface is destroyed, unmapped, or loses the seat's keyboard
+      focus, the keyboard shortcuts inhibitor becomes irrelevant and the
+      compositor will restore its own keyboard shortcuts but no "inactive"
+      event is emitted in this case.

+          Request exclusive keyboard focus if this surface is above the shell surface layer.
+
+          For the top and overlay layers, the seat will always give
+          exclusive keyboard focus to the top-most layer which has keyboard
+          interactivity set to exclusive. If this layer contains multiple
+          surfaces with keyboard interactivity set to exclusive, the compositor
+          determines the one receiving keyboard events in an implementation-
+          defined manner. In this case, no guarantee is made when this surface
+          will receive keyboard focus (if ever).
+
+          For the bottom and background layers, the compositor is allowed to use
+          normal focus semantics.
+
+          This setting is mainly intended for applications that need to ensure
+          they receive all keyboard events, such as a lock screen or a password
+          prompt.

+        <description summary="request regular keyboard focus semantics">
+          This requests the compositor to allow this surface to be focused and
+          unfocused by the user in an implementation-defined manner. The user
+          should be able to unfocus this surface even regardless of the layer
+          it is on.
+
+          Typically, the compositor will want to use its normal mechanism to
+          manage keyboard focus between layer shell surfaces with this setting
+          and regular toplevels on the desktop layer (e.g. click to focus).
+          Nevertheless, it is possible for a compositor to require a special
+          interaction to focus or unfocus layer shell surfaces (e.g. requiring
+          a click even if focus follows the mouse normally, or providing a
+          keybinding to switch focus between layers).
+
+          This setting is mainly intended for desktop shell components (e.g.
+          panels) that allow keyboard interaction. Using this option can allow
+          implementing a desktop shell that can be fully usable without the
+          mouse.
