Recolored Pura?

They were in the catalogue for a day or two. Did anyone else notice this?
I bought some, and now it is gone. Black and aqua are still there but pink, red, beige, and yellow aren't. Are they worth anything? They were all 1 credit but the beige were 5 credits, weird.

Here's a picture of them in storage, didn't think of getting a catalogue screenie.

all colours accept beige have been on sale before.

Beige might of been in a deal or something..

Beige was on sale yeterday for 5 credits along with all those colors which were one credit. Also the beige said null as its description.

Yeah I noticed that too, all the colours.

Seems a bit odd. :S
Why not release all of them at once, instead of just one module? xD
