Computer use binary and people use decimal. They are not easy to convert between.
Hexadecimal and binary are though: 1 byte (8 bits) can store 256 different combinations of numbers, which is the same as 2 hexs (FF).
You can make a huge number of different colors by saying how much red, green and blue you want in the color. Each color has 2 columns that can hold the numbers 0-F.
The color order is Red, Green and Blue.
F means full color, 0 means no color, so Red = #FF0000, Green = #00FF00 and Blue = #0000FF. All colors at full intensity make white #FFFFFF, No color makes black #000000
