Why is chromate yellow and dichromate orange?

Yellow chromate and orange dichromate are in equilibrium with each other in aqueous solution. The more acidic the solution, the more the equilibrium is shifted to the right towards the dichromate ion. As nitric acid is added to the chromate solution, the yellow color turns to orange.
