The colors of namespaces in the charts and graphs could relate to each other in the following pairs:
Main | Talk |
User | User talk |
Wikipedia | Wikipedia talk |
Template | Template talk |
File | File talk |
Book | Book talk |
Category | Category talk |
Help | Help talk |
Portal | Portal talk |
... | ... talk |
Eg. the color of talk namespace could be the same hue and saturation but lighter than the related non-talk namespace color.
