trick question without you realizing it. If it was simple dominant it wouldn't pop up because your entire colony would be recessive for clear.
HOWEVER, having said that- I can only speak from Neo experience since that is what I've concentrated on selectively breeding- color is MUCH harder to breed out, than breed IN.
IN other words, if you choose to try your hand at selectively breeding these, you should have a much "easier" time making the color pop up. Even if co-dominant and it takes over color attributes, you are still going to have a good go at this.
The first step is to breed more of these.
2nd step is to breed for color intensity.
If in the f2 you have a non-lethal homozygous expression, your color should be able to breed true and intensity improved rather rapidly with good selection!
