Android doesnt read olive green color and all other colors are different then web colors.

Andorid app doesnt displayes colors well. Namely, olive green. It is displayed as white.
But it reads grey and some others. I tried them few, not all. 
Also, colors that it does read are similar to Web colors but acctualy are totaly different! 
So: Olive green is not displayed in Android and all other colors are way different then Web colors.
It used to be fine and same. What is messed up?
