I want to color classes in my class diagram, based on a certain criteria, and then display a legend, that would look roughly like:

Legend with colors

If I could add an HTML table within PlantUML's legend and endlegend, I could achieve this by changing the cell backgrounds. However, adding the HTML <table> doesn't work. I also tried using PlantUML's salt to insert a table, but I couldn't find any way to color the cells of the table.

Is there any way to achieve this?

I've tried nfec's solution and it was not working for me, but it started me off on a solution that did work. Here is what I got:

legend right
    |Color| Type |
    |<#FF0000>| Type A class|
    |<#00FF00>| Type B class|
    |<#0000FF>| Type C class|
endlegend

This is how it looks like:

Legend color table
