No, colour is just an indication of temperature.
A colour cannot be assigned to a young star. It all depends on the mass of the star as to what temperature it will reach, and this temperature will dictate what colour it is.
An O star will have a blue to blue-white colour.

Yellow

When a star colour is blue, then the temprature of the surface can go from 20,000c to 50,000c. When a star colour is white then the temprature of the surface is around 10,000c. If a star colour is yellow like the sun then the temprature of the surface is around 6,000c. If the star your looking at is red then it is not really hot, the temrature of the surface can go up to 3,000c. Hope i helped :)
