Yello Cup Coral turning green

It might also have somthing to do with your lighting. I got a light yellow/tan T. peltata that was under 250w MH at the LFS. I put it under 110w PC, and it turned bluish/green. When I added 250w MH, it went back to its' original color.

The easiest way to tell is by looking at it -- if it looks too good to be true, it probably is. There are many types of corals that are now dyed, even some anemones. I've seen some long tentacle anemones that are bright yellow as well. However, keep in mind that rose anemones and some carpet anemones have wonderful color, but they also have a big pricetag. Think twice when you see something that looks really cool but isn't very expensive.
The "dying" thing is very unfortunate, and the only thing we can do right now is to educate everyone so that they don't buy these "fake" corals so the demand will go down.

Yes they are dyed, and they should not sell them unless they advertise them that way. Its very misleading, and I've seen a $30 coral go for over $100. I also saw a beautiful bright yellow sebae anenome and it was going for $300. I asked the owner if it was indeed dyed, he played dumb and said I'm not sure? A week went by and I was told it had died.

I am not saying they don't dye them yellow but there are pictures underwater in the wild of yellow Turbinaria mesenterina and for years its been sold as yellow Tubinaria sp. in LFS. This is also called Cup coral or Pagoda , could this not be what some LFS calls yellow cup. Wouldn't the less expensive more common Turbinaria peltata , the green/brown one ,be the one that is dyed yellow. So there is a yellow cup coral or is my thinking wrong

SFLA_PB, you are thinking correct as there are yellow cup corals. It is very difficult to tell the difference with the dyes they are coming out with these days. Most color changes, from yellow to green or brown is due to a more acceptable light regime. If you'll notice, yellow polyps will go the same route with adequate lighting. You will usually be able to tell a dyed after several weeks to months when the coral slowly begins to have a faded color, like flaking off, and the beginning of disintegration.
So you're telling me that every time a coral changes color that you automatically assume that it's been dyed, huh? Let me show you a few Acropora sp that have changed color due strictly to lighting...
No one has apparently asked this question yet so I will: what lighting did that guy have that yellow cup coral under?

Good lord people, quit generalizing especially when referring to common names instead of actual species. "Cup Coral" is a common name used to reference almost all Turbinaria sp.
Although there have been some cases of dyed T. peltata, by generalizing all "cup corals" you are also suggesting to everyone, especially newbies who might not know better, that all T. reniformis (also a "cup coral" but more commonly called "yellow scrolls") are also dyed which is a totally false statement.
