usage

1. use the color picker button to open the full color selection dialog
2. click “Pick from Screen” to grab a color from anywhere on your screen - your cursor will change to a crosshair, click on any pixel to select its color
3. click “Copy to Clipboard” to copy the hex color code
4. click “Save…” to save the current color to your favorites list
5. expand “Saved Colors” to view and manage your saved colors

saved colors are stored in ~/.config/kjagave.json as json.
