Stroop test (not) in Russian?

Anna is showing her friends a test using her new MIG computer. Olya takes the test.

...

Anna: Read the colors.

Olya: But they’re not Russian. They look like English words.

Anna: That doesn’t matter. Don't read the words, instead say the color each word is displayed in, as quickly as you can.

Olya: красно, голубо, пурпурово, желто, пурпурово, красно

Anna: Perfect score.

Olya: But what does it mean?

Anna: You are highly intelligent and have no signs of schizophrenia nor anorexia.

Olya: But I can’t read English.

Anna: Oh, that doesn’t matter, this is a color test.
