Is there a way to find a lighter and darker shade of a RGB color programmatically?

[Paul Hibbert]

Hey Keith,

One site that could help you is Scott Rossi's tactilemedia.com he has some great tutorials and the 'Color Slider' tutorial should give you all the info you need to convert your colour data into HSB (HSL), then you can just compare the brightness values and respond accordingly.

The tutorial page is here; http://www.tactilemedia.com/site_files/software/tutorials.html
