How the three sliders work

GeoPaint from Geotrivia shows a flag with one color missing, and you mix that color back with three sliders. Knowing what each slider does saves a lot of fiddling.

Hue: the color family, red, orange, green, blue and so on
Saturation: how strong the color is, bright paint or washed out paint
Brightness: how light or dark it is, daylight or shadow

Flag colors are not all the same

Two red flags are rarely the same red. Some flag reds lean toward orange, others toward deep crimson. Blues range from pale sky blue to navy. Before you touch the sliders, picture the flag and ask: is this a bright, light color or a deep, dark one?

Set the hue first. Get the family right before anything else.
Then saturation. Most flag colors are strong, so start high.
Brightness last. Small moves here change the score a lot.

Practice and the archive

The daily flag is free. Older days live in the archive, which comes with Geotrivia Pro. If you just want more color practice, Toon Tone uses the same idea with cartoon characters.
