As a color-blind person, most of the time when stuff on screen was only differentiated by color (like red/green status indicators), the go-to-tool would be the system’s digital colorimeter for me.

It was tiresome to have to launch an extra application and inspect RGB percentages to derive what color I was supposed to see.

The colorimeter I made activates while holding down an inconsequential modifier key on the keyboard and shows the name of the color.

Now I can also quickly double-press that modifier key and copy the color value to the clipboard.
