Colllor is a free-to-use web application that helps us to create a more consistent color scheme.

For any given color, the app displays the exact value of darker shades of it (not something that looks darker but the ones that derive from the same color where all have a common denominator sharing hue, lightness or saturation values).

Colllor

Using Colllor, we can easily explore tints, shades, tones or similar colors and mix colors to create new ones.

It understands both the HEX values and color names. Also, you can instantly pass the color name to the URL (like http://colllor.com/blue) to get started quickly.

P.S. There is also a Chrome application for it.
