Google translate seems to think those are blauw and cyaan, respectively. I'm not sure why it decided to translate into Dutch though...
But translating it to "dark/light blue" would be incorrect, as the lightness is not an important part of the words. It is just that Russian speakers are forced to specify the lightness, similarly to how German speakers are forced to specify the sex of their neighbor (Nachbar/Nachbarin). In most cases, Nachbarin should simply be translated to "neighbor".
But that's likely not the traditional meaning of it, in whatever language. So I don't assume that I know what cyaan is.
