That can vary. The color alone is not enough to establish the age of a star.

What is the color of a dying star?
Young stars are mostly blue. Young stars, at the peak of their temperature, represent the color blue because blue is the hottest color of known stars.
What are some possible colors of large mass stars?
Large mass starts are blue (when they are young) or Red (when they get old).
Are blue stars younger or older?
Blue stars can be expected to be young as they do not last as long as other stars do, often only a few million years. That said, a lower mass star could still be just as young.
Is a blue star the youngest star?
No. While blue stars generally do not last as long as others, it is possible to find relatively young yellow or red stars.
Are all young main sequence stars blue?
No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.

Why do stars turn blue?

Do spiral galaxies have young stars middle age stars or old stars?
It has all types of stars with different ages
