Rainbow carrots

I have grown White satin, Solar Yellow, Red Samurai and Cosmic Purple.  I found the yellow, white and purple ones were  very 'carroty' in taste which I like.  The red ones were unremarkable and didn't grow well.  I intend to sow the yellow, white and purple again.

Interesting.

Do they keep there colour when they are cooked?

Yellow & white keep there colour when cooked . Purple depends on variety. Purple haze for example is only purple skinned. Purple sun is all purple and keeps it’s colour when cooked. There are other varieties that stay purple.
