RGB to HEX rules
A HEX color code stores the red, green, and blue channels as two hexadecimal digits each.
- RGB(255, 0, 0) = #FF0000
- RGB(0, 128, 0) = #008000
- RGB(255, 255, 255) = #FFFFFF

RGB to HEX notes
- Each RGB channel must be between 0 and 255.
- HEX codes are case-insensitive, so #ff0000 and #FF0000 represent the same color.
- Alpha transparency is separate from standard 6-digit HEX and may appear as 8-digit HEX in some tools.
