Kolorz

Relax. Pick a color.

Kolorz is a simple game, elegant game to help teach hex colors.

You've probably seen them before, they are the things in HTML that look like #F0D9EA. If you don't already understand hex colors, they're quite simple. They are just three values, red, green and blue, written in "base-16", also called "hexadecimal" or simple "hex".

In base-16, every digit goes from 0-15 instead of 0-9. Since we don't have enough numbers in our language to go past 9, we use the letters A through F instead. When you count in hex, the numbers go like this: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. If you want to write a "10" in base-16, you's simply write an "A", see?

Otherwise, they work just like normal numbers. If you wanted to write a number like 161, for example, that would look like "A1", since there is an "A" (i.e. 10) in the "16's place" and a "1" in the "1's place". 10 times 16 is 160, plus 1 times 1 is 161, easy!

Hex colors are colors made up of three different 2-digit hex numbers. The first two are red, the second two are blue, and the third two are green. #FF0000 is all red, while #0000FF is all blue, see? Mixing red and blue (such as #550055) will get you a shade of purple. Got it?

Kolorz shows you a color written out in hex, and you try to guess which one it is, and that's it.

Have fun!
