Currently, no. However, there is some code/comments that suggests it MIGHT be coming someday…
edit: Oh, interesting… Found the new colors possibly… (I was going to work on something and just happen to notice it.)
IDS_COLOR_BEIGE “Beige”
IDS_COLOR_DARK_GREY “Dark Grey”
IDS_COLOR_LIGHT_BLUE “Light Blue”
IDS_COLOR_SKY_BLUE “Sky Blue”
IDS_COLOR_DARK_PURPLE “Dark Purple”
IDS_COLOR_MAROON “Maroon”
IDS_COLOR_BROWN “Brown”
edit: Although, that’s only 7? hmm… Wonder what the 8th color would be?
