Colour Contrast Analyser 3.5.4
Some colors do not mesh; Colour Contrast Analyser helps you to visualize what the combo will look like before using it on a webpage, for example.
It is available as a portable download, so you can have it available even when away from your desktop. The interface is organized, allowing you to pick a color (by the pixel) easily. You have the option to view the selected color in HEX/HEXa, RGB/RGBa, HSL/HSLa, and HSV/HSVa. The corresponding values are boldly displayed and can be copied.
Colour Contrast Analyser additionally provides WCAG results at the bottom of the interface with descriptive examples. It is easy to use but provides a wealth of color info for any user needing color values.
