Answer 1

Do you mean how to make colors using Hex-value?

Answer 2

In hexadecimal, colors are anything from #000000 to #ffffff so with css you would use:
color:#000000; for black
color:#ffffff; for white
color:#ff0000; for red
color:#00ff00; for green
color:#0000ff; for blue
for lighter red, green or blue you would increase the 0’s
for darker you would reduce the f’s

Answer 3

yes
