VisitLeonardo vs qualpal
What both publish
| Fact | Leonardo | qualpal |
|---|---|---|
| Color accessibility | The tools can cycle through colors for colorblind safe palettes and compare color difference across color vision deficiency types. | Palettes can be adapted using color vision deficiency simulation. |
| License | The project is licensed under Apache V2. | The source repository states that Qualpal is available under the MIT License. |
| Limit | Generated contrast ratios may be slightly higher than the requested ratio because available RGB colors and color space interpolation constrain exact values. | Qualpal does not consider aesthetic factors such as color harmony or complementary colors when choosing colors. |
| Purpose | Leonardo creates, manages, and shares accessible color systems for user interface design and data visualization. | Qualpal is a C++ library for generating qualitative color palettes with maximum perceptual distinctiveness, especially for data visualization. |
