Within certain parameter's, then yes.
The colour and thus temperature of a star gives an indication of a stars age. The hotter it is, the younger it is.
A blue supergiant can be aged within a few million years, whereas a red dwarf, we have no idea. A billion years or a million - we will have no idea.

∙ 13y agoIn almost every case, whether it is an instrument actually on the planet, or a telescope looking up from the earth, scientists use some variation of an instrument called a spectrometer. Spectrometers take a signal from whatever they are looking at (whether it is a rock, or a cloud or a whole planet or a star or a galaxy or a nebula, etc.) and spread the signal out into its components. Most spectrometers work with light and are a lot like extremely good prisms; they take the light coming from some object and separate it out into its colors. This is useful because it turns out that every element on the Periodic Table only gives off light of a few certain colors
