Shade generator
The shade generator makes it easy to create shades and tints that are perceptually uniform and accessible.
Setting up the generator
First, select the number of shades you need using the + and - icons under the Number of shades title.
After that, select the lightness range. Use the Start and End sliders for that.
Nice lightness values
By default, the generator creates shades evenly distributed in the lightness range. This creates shades with odd lightness values (40.14, 60.23, etc.). To avoid this turn on the Nice lightness values toggle. Now the generated shades will have lightness values aligned to fractions of 2.5 (20, 27.5, 35, etc.)
Generate
When you are happy click on the Generate button.
Exclude color
Every time you generate the whole palette is regenerated (except for the source colors). To avoid overwriting some colors you can exclude them from the generator by unchecking the Include in generator option. When some colors are excluded you can't adjust the number of shades.
Hue shifting
After generating you can further customize each color to make it just right. Start by clicking on the Hue shifting button.
When shades are generated they all have the same hue value. By slightly changing the hue value you can achieve even better outcomes - this is called Hue shifting. In Atmos, you can do this by using the hue shifting chart.
The chart visualizes the shades from darkest to lightest on a bezier curve.
3 points make up the curve:
- Darkest shade
- Source color (can't be moved)
- Lightest shade
To adjust the curve either move one of the points or handles.
