Tint & Shade Generator

Easily make tints and shades in 10% increments.

What is the Tint & Shade Generator?

The purpose of this tool is to accurately produce tints (lighter variants) and shades (darker variants) of a given hex color in 10% increments.

Testing shows that it matches the way Chrome DevTools and the classic W3Schools color picker calculate tints and shades. As far as I can tell, there are no other applications that get the calculation correct and produce the tints and shades so simply.

When would I use this?

It's best used when you already have a base color palette but would like complimentary colors for gradients, borders, backgrounds, shadows or other elements.

Why 10% increments?

That’s the standard I developed for my design process at Texas State University and in other projects. I think choosing tints and shades based on a flat percentage is a clean, reproducible way to augment brand palettes and produce designs with depth.

Calculation Method

The given hex color is first converted to RGB. Then each component of the RGB color has the following calculation performed on it, respectively.

  • Tints: New value = current value + ((255 - current value) x tint factor)
  • Shades: New value = current value x shade factor

The new value is rounded if necessary, and then converted back to hex for display.

Example Calculation

Let’s say we want tints and shades of Rebecca Purple, #663399.

10% Tint

  1. #663399 is converted to the RGB equivalent of 102, 51, 153
  2. R: 102 + ((255 - 102) x .1) = 117.3, rounded to 117
  3. G: 51 + ((255 - 51) x .1) = 71.4, rounded to 71
  4. B: 153 + ((255 - 153) x .1) = 163.2, rounded to 163
  5. RGB 117, 71, 163 is converted to the hex equivalent of #7547a3

10% Shade

  1. #663399 is converted to the RGB equivalent of 102, 51, 153
  2. R: 102 x .9 = 91.8, rounded to 92
  3. G: 51 x .9 = 45.9, rounded to 46
  4. B: 153 x .9 = 137.7, rounded to 138
  5. RGB 92, 46, 138 is converted to the hex equivalent of #5c2e8a
