The next two seedlings are showing good color intensity. The orange yellow one almost glows. It is a Hulthemia cross, but doesn't show a blotch. Even so, I'm keeping it for it's bold color. The purple one is from a cross of 'Midnight Blue' X "Blue For You'. I have four from this cross that I am watching. The purple is more intense than what the photo shows (purples are difficult to capture correctly).
The last seedling shown below, is the least exciting color-wise but might have the most promise since it has 'Knock Out' on one side and one of my cleanest seed parents on the other side.
