How to generate a legend with colors in PlantUML?

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

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?

This is not perfect, but you can use some creole table.
(see )

class foo

|= |= Type |
|<back:#FF0000>   </back>| Type A class |
|<back:#00FF00>   </back>| Type B class |
|<back:blue>   </back>| Type C class |



There are some drawing artifact, but is it what you are expecting ?

The colours in the legend are displayed in png file but are not displayed in svg file.
