I don't charge for Color Cop. It's yours for free and it will stay that way. I've had a lot of fun creating it and learning new things along the way. If you are happy with the app and would like to show your appreciation, please donate.
If you already have a PayPal account it's even easier to make your secure donation for Color Cop. Simply follow the link below (click on the PayPal button):
Failing that, you may send me an email asking for my posting address, if you want to contribute in a non-monetary fashion.
