Colorbase is a simple utility to colorize DNA sequences. Pipe data through it to colorize for visualization.
For example, run the following command:
echo "ACTGGAcaaggt" | ./colorbase
or
echo "ACTGGAcaaggt" | ./colorbase | less -R
Note: less requires the -R option to display colors; if you omit it, you will see the raw color commands rather than colorized text.
