To store the hexadecimal number FF, we need to convert it to binary first. FF in hexadecimal is equivalent to 1111 1111 in binary, which requires 8 bits to represent. Each hexadecimal digit corresponds to 4 bits in binary, so two hexadecimal digits (FF) require 8 bits to store.
The hex code #FF0000 is pure red. Hexadecimal colors are given in Red, Green, Blue as a number in the hexadecimal number system. The number FF, in hex, is the same as the number 255 in decimal. Pure blue? #0000FF Pure green? #00FF00 And any of the 16 million or so other colors hex is capable of.
The hexadecimal of black, assuming that "black" is an ASCII character string is 0x626c61636b. If you mean RGB, it is R=00H, G=00H, B=00H, or 000000H combined.

Hexadecimal color values are representative of variations in Red, Green and Blue (RGB) color, within the structure of the Hexadecimal, or Base 16 positional numeral system. Within this system, values are represented 0-9, and A-F (representing 11-16). The structure of hexadecimal color value is actually three sets of two digit hexadecimal numbers (e.g. 0F 28 7D). The first value set determines the amount of red, the second green, and the third blue. Within each set, the first number is in value increments of 16, and the second in increments of 1. Where "12 34 56" represents 18 levels of red, 52 levels of green, and 36 levels of blue. You can get a pretty good feel for this color system by playing with the tool over at ColourLovers (see related link.)

255 = ff
100, which equals 163 in hexadecimal.
hexadecimal numbers are the a positional numeral system with a radix, or base, of 16.16 distinct symbols are used in the hexadecimal numbers.
The color charts many see on the web are HTML codes which contain both numbers and letters. The simplest answer is that both the numbers and letters are used in the hexadecimal numeral system. For example, FF in hexadecimal equals 255.
Eight.
Oh, dude, you're asking about the highest 8-bit number in hexadecimal? That would be FF, which is 255 in decimal. It's like the king of the 8-bit numbers, ruling over all its binary subjects with its hexadecimal crown. So yeah, FF is the boss in the 8-bit world.
111111 in binary is 255 in decimal which is FF in hexadecimal (i.e. 15 units and 15 16s)
