I found a very cool utility. It’s called Pixie and it’s free.
Pixie is an easy-to-use, fast and tiny utility designed especially to fit the needs of Webmasters and Designers. Its a colour picker that includes a mouse tracker. Run it, simply point to a colour and it will tell you the hex, RGB, HTML, CMYK and HSV values of that colour. You can then use these values to reproduce the selected colour in your favorite programs.
Now why should you care about this? I’ll give you two applications I’ve already used it for.
1. If you do any of your own web or blog design work and want to match colors in a logo or on another website, when you open and hover your cursor of the color you want to match, the hex code will be displayed. You need the hex codes in order create the precise colors you want on a web page or blog. This is especially important if you have unusual colors, outside of the standard that may be available in a color chart for you to click on.
2. If you display AdSense on your blog or website, you probably know it’s been proven that you get more clicks if the ads are well integrated on your site. Meaning: it’s important to match the background color of the AdSense ad strip to your website. (See how it looks here.)
When you set up an ad strip, you can customize it so the background and fonts are any color you want. In order to match to your web page, it’s important to know the hex code so you get a perfect match.
Thanks to AudioAcrobat for this tipping me off to this cool utility.
