I had 8 / 10 pink / purplish colour ones... Ranging from deep deep purple to lighter purple to pink etc...
The green phenos are much more powerful. Many of the coloured phenos tend to be weaker than the green ones.
You gotta ask yourself, do you want to grow 7,5 potency points purple ones or 9.0 potency points green ones.. Hard choices.. My mate ditched my largest yielding purple pheno after a few runs b/c he felt that even though its pretty, he rather have something more potent in the place of it.
Some of the purple ones have crazy flavour profiles, but only a few of them yield well. Some of the smaller yielding purple phenos have had some of the best flavours I've tasted in cannabis ever.
