Detecting Colours - ColorZilla

You can pick the colour of an image or logo off a web page using ColorZilla.

Install the Chrome extension or Firefox extension and then just click the extension icon, picker and choose an icon or image or area from the web page.

For example, I used this to find out the exact yellow colour of the Miro.com logo as FEDD33.

This would be hard to determine by guessing the colour, and if you just picked the generic yellow colour it would come out as this:

Whereas with the hex colour detection of the exact hex code of FEDD33 it comes out as this, which is a very diffferent yellow:

Terminal Colors Programs

I wrote a couple programs to show basic colours on the terminal background vs foreground:
