They are rainbows. you can sort of see it in the pictures but it's hard to capture it as getting the white balance right under the LEDs is difficult and I'm not playing with the pics in photoshop. But they have the green/white speckled mouth and the tentacles go noticeably from green to orange to pink. These aren't the two colour green and pink ones.
They are like these (but with less Kessil lighting and photoshopping of the pics):
