What is Contrast-Finder ?
There are lot of tools to find a good contrast on the web, but no one to suggest valid contrasts.
Checks if the contrast is valid
Contrast-Finder is a tool which computes the contrast between two colors (background, foreground) and checks if the contrast is valid.
Suggest correct colors contrasts
When the contrast is not valid, the main target is to suggest some correct colors contrasts.
The first one is "valid colors". The result is a wide range of colors. This algorithm is very helpful if you are not sure about the hue of your initial color.
The second one is "valid colors and very close to initial color". The result is a list of colors close to the original color. The aim is to have a valid color with a contrast as close to the selected ratio as possible.
