I wanted to get to this earlier, but I ended up with a nasty sinus infection and have done little more than try to keep up with my email.
So, what are my thoughts on the subject? You all knew that I would have something to say. 
The first line of the product description for Premo! says, “Premo Sculpey is an artist’s dream come true! “. While that may have been true, it is no more. When you take away two primary colors (cobalt blue and zinc yellow), you take away an artist’s color palette. Polyform says it will have recipes for cobalt blue and zinc yellow. How in the hell can you mix a primary color? Well, you can’t. They will not be exactly the same, nor will they mix exactly the same.
Artists mix their own colors. It is part of what makes their work unique. I recently posted on the subject of how important color is to design and how the colors right out the package are too intense for most things.
So, what can we do? Write or email Polyform Products. Let them know how important it is to keep primary colors (cobalt blue and zinc yellow).

Hi Chris, Although the new color additions are a very exciting thing, I am very upset to see that some of the artist based primary colors which are vital to color mixing have been discontinued. So to stop that I have put together a virtual petition to !SAVE cobalt Blue, Zinc Yellow and Sea Green! We need to get as many comments as possible so that we can save these colors (and countless color recipes) from extinction!The link by my name will take you to where the comments are starting to pile up. But we need as many as we can get. I would like to see 1000+ names in there. Will you help me?
Let your voice be heard!!

Thank you Chris for this post. It worked beautifully because we did it! It was because of everyone banding together like this, that Polyform decided to keep Cobalt Blue and Zinc Yellow. (Still working on the Sea Green but this is definitely a good thing!) Thanks again for your support!
I am copying this message I wrote as I think word needs to get around about this. The publicing of the news is so conviently in Xmas time that I am afraid people will miss this if we do not intentionally spread the word.
I stumbled into polymer clay express blog
http://pce-artway.blogspot.com/2010/12/clay-news.html
where there is a text “Great News!!!
We will be carrying Zinc Yellow and Cobalt Blue Premo throughout 2011!! We are one of three companies that will be doing so. ”
so when polyform promised that they will continue those colours they actually, IMO, lied. There is no promis about continuing then further and also this this does not help my situation a bit as I am selling clay for my customers in Finland and not buying it retale for my own use. I am dissapointed and this truly ruins my xmas
This is what I posted to polyforms facebook page
http://www.facebook.com/pages/Polyform-Products/106551216055451
“I just readed from polymer clay express that actually, on contrary to your promise, you are NOT going to make the cobolt blue and zinc yellow available to all customers as we here in europe that are selling the clay are not going to buy your clay from retalers.
I am dissapointed on your desicion and I think you lied when you tried to convince the audience that you are “keeping” the zinc yellow and cobolt blue. “
