What is Colllor?
With Colllor it is much easier to generate a consistent color palette with just a few clicks. You should use colors consistently, so you have a common look and feel throughout your design. All the alternative proposals produced by Colllor derive from the same color and they all have a common denominator sharing hue, lightness or saturation values. This tool will let you find the exact value of darker shades of any color, not just something that 'looks darker'. That will be a huge step towards professionally looking color combinations.
