You can use specify fill and line colors either:
A special color values: transparent can be used, synonym of transparent black ( #00000000).
Example on Gantt Diagram:
@startgantt
[Activity1] lasts 5 days
[Activity2] lasts 5 days
[Activity1] is colored in White/Red
[Activity2] is colored in Silver/SeaGreen
[Activity1] -> [Activity2]
@endgantt
Example on Sequence Diagram:
@startuml
actor Bob #Red/Yellow
actor Alice #FF0000/FFFF00
Alice -> Bob : hello

This uses Color Gradient, see next section.

You can also use color gradient in background, with the following syntax: two colors names separated either by:

The special value automatic can be used for font (text foreground) color. In that case, the color is either black or white, depending on the current background.
@startuml

}
class classB #fff {

A user has recently created an image to display all names colors used by PlantUML. (We thank him by the way!)
So a new feature has been added to print all those colors using a special diagram description:
It is also possible to print a palette of colors close to some other color (using its name or HEX value).
