BLOCKS Sequence Logo colors

## About sequence logo colors:

The amino acid colors in sequence logos help visualize the chemical and physical properties of specific positions and areas in the Block. Amino acids each have a number of different properties. Thus there are several ways to group amino acids.

In the file defining the colors of the logo characters, lines that begin with an asterisk [*] are comment lines. Other lines define a character color. Each such line contain 4 parameters - the character defined and its red, green and blue (RGB) components defining its color. The RGB values are real values between 0 and 1. A value of 0 means black and a value of 1 means the most bright. Characters which are not defined will be black.
