Also, Why is FF 255?

To denote a hex literal in C 0x was adopted as the prefix and carried on to its successors. 0xFF = 15*16+15 = 255. Since FF(hex) = 255(dec), it follows that 0xFF = 00FF if leading zeroes are not suppressed. Therefore x stands for 0.

Hex colors

When making a new document in Photoshop you might choose to make it with “8 bit” color, which means that each pixel is represented with eight columns worth of binary digits for red, green, blue and the alpha channel: 0b00000000 to 0b11111111 = 0 to 255.

What is FF in hexadecimal?

I thought I was with it until I read that FF = 255. I understand that hex is used because it allows for a higher numerical value in a single character space. And it counts 0-9 like normal, and then, A=10, B=11, C=12, D=13, E=14, F=15, and then starts over at 10.

How do I read 0xFF?

The letters represent those digits that correspond to 10 through 15 in base 10. So, 0xFF = (15 * 16) + 15 = 255. 0xAB = (10 * 16) + 11 = 171.
