Yellow for toddlers???

My youngest daughter will be 3 in 6 days!!! Her favorite color is yellow so I wanted to try to find her yellow everything (outfits, shoes, glasses, purse, etc..) but why is it so hard to find yellow??? They have EVERY other color in almost everything except for yellow. I also find it odd that my daughter’s favorite color is yellow. She is definitely unique. Anyone else love yellow?
