Can the color of an alien sky be calculated solely from atmospheric composition and the star's (or stars') spectral type(s)?

What exactly are the relevant numbers for such a calculation, and can it account for the color of the sky?

By sky color, I mean the day to day hue that humans (or something else with very similar eyes) would experience if present on the surface. Earth is "light blue" or "robin egg blue", I don't need all the possible variations for any conceivable weather condition. Oh, and this being for a computer game, it'd be nice if it was easily convertible to rgb() colorspace.

I'll have the star or stars' stellar classification. The planet's distance from the star(s), its atmosphere down to the 0.1% components (give or take), and a whole host of other numbers that don't seem relevant. I'm hoping to be able to generate crude landscapes from this. If I'm missing the relevant data, I can work that into the simulation possibly and have it available.
