Flowers try to attract insects that will pollinate them. They do this by being bright colors that insects will notice, and by having sweet smells that insects like. Yellow is a common color for flowers because it is bright and easy for insects to see.
Why are some flowers yellow? From Cristin C. 1st grade?
There are different pigments that can cause the color yellow, check out this web page:

As for why they are yellow chemically, the light that comes from the sun has many different colors in it. Those chemicals reflect the yellow light and absorb the other colors so we see the yellow.
