Purple just does not work for me as with the orange ones!

Colour means different survey providers. In spite of that, you can find the same survey in two non-colour-identical survey channels. It might happen because some research companies may use two or more providers. For example, the company AAA could use both survey providers BBB and CCC, thus Rewardia member would meet this in both Blue and Orange survey channels.

Different colors, different points. I don't really know the significance.

after a while you know which to choose. Some colours I get screened out every time. Edited 17-Aug-22 16:43pm

Doesn't seem to be any - any of the surveys I do can appear in all colours

i just start at the top and work down I get a lot of points for being screened out they all add up

Yeah, it's confusing. Green, pink and purple all pay up to 1200, red = up to 1000. When I log in in the morning, it states that there are no blue surveys for me, but I am free to choose any other colour. For some reason it thinks I need blue surveys. Perhaps I have qualified for blue. I'm confused and feeling blue.
