They are all of those colors. They are cream, light yellow with very light pink/laverder veining. These pictures are from first year plant. I have to say that I am not impressed with the bloom. I hope they get better in subsequent years. Let's just say that if I were to see this plant at the garden center with blooms, I would not be tempted to buy it.

Here is another shot of a different bloom Got two blooms this spring.

Thanks for the feedback. They are kind of odd looking blooms. I feel a bit the same way about Kopper Kettle - it's got quite an interesting mix of colours, but I don't love the overall effect.
