Performance differences between color declarations?

Question

In CSS we can use several different methods to define a color:

• Color word: red
• Hexadecimal: #FF0000
• Red/Green/Blue

Answer 1

Edit: Each process has to get down to a binary value for r, g, and b. Hex and rgb bytes are already set up for that, so I guess they might actually be roughly the same speed. The rest have to go through a process to reach a hex/rgb value

#FF0000 = memory values of: 1111 1111 0000 0000 0000 0000

rgb(255,0,0) = memory values of: 1111 1111 0000 0000 0000 0000

Both cases are most likely stored in 3 int variables. So the real question is, which is faster to process into binary values for these integers? HEX or DEC? I think HEX, but I can't back that up. Anyhow, the code just takes the binary values of these variables.
