For me there is no doubts about it . Envy tangerine has deepest and brightest colors than Tangerine Dreams. Both are at my aquarium under the same conditions and have been there for more than a year.
That would be fair. Cornbred's has better color but that may be because of the angle. JF is taken from top and Rich's is more at eye level. Anyone having clams knows the angle of view makes a huge difference.
I know lighting makes a lot of difference to coloring. When i was at WWC they had many large colonies of high end chalices all in the same tank. JF tangerine was one. The same chalice had 2 different brightness shades to body depending on the angle of lighting it was receiving. The first picture it may be cornbred's on the right side of picture. If so it appears to be lower in the tank.
