Weighted color values (as opposed to the typical 33.33% each):Hint: you'll probably have something in your code like luminance = r * .3 + g * .59 + b * .11
- Red → 30%
- Green → 59%
- Blue → 11%
| If the luminance is... | Print out the statment... |
| Less then 10 | That's going to be awfully dark |
| Greater than or equal to 10 or less than or equal to 50 | A little dark. |
| Between 50 and 200 | Looks like a good range |
| Greater than or equal to 200 and less than 250 | Getting kinda bright. |
| Over or equal to 250 | AHHH! MY EYES! |

| Less then 100 | 25% |
