Tool to do full-screen color sweeps to diagnose color behaviors. Clicking on the surface with a mouse closes the tool.

In the default mode, the mouse controls HSV: Horizontal position is hue, vertical movement is saturation, scroll is value. With -m rgb, horizontal movement is red, vertical movement is green, scroll is blue.

-h, -s and -v can be used to assign a static HSV color value as 3 floating point numbers between 0 and 1. With -m rgb, the options are -r, -g and -b to assign a static RGB value.

-c 0.001 causes the tool to cycle through all hues at full saturation at 0.1% hue change per frame for e.g. pixel refresh.

Requires zwlr_layer_shell_v1, wp_single_pixel_buffer_v1 and wp_viewporter.

#How to use

meson setup build
ninja -C build

Move the mouse, scroll, and click to close.
