Update colours of the Stroop task or show the colours in the instructions

[yancheva]

Hi Maria,

I thoroughly enjoy participating in the Talk2Me sessions.

I am, however, having much trouble with the stroop section as I find the blue and purple hard to distinguish from each other. I will say "blue", then notice that the next screen is more blue and the previous one was actually "purple". I could kick myself afterwards. Is there anything that can be done, like maybe show a sample of each before the test? Anyway, no worries. This is just a recurring problem I have with this segment and I needed to vent.

Thanks for listening,

Katalin
