Is there anywhere that I can purchase colored sesame seeds?

if you mean white and black..most asian stores will have it, also Wholefoods.

I know exactly what you are talking about.  When you want lots of color but you don't want to use sugar toppings, these sesame seeds dyed with food grade colors are the perfect substitute.  These seeds come in white, yellow, green, orange, red, pink, purple, blue, black, and confetti.

Another place you can try is the Brazilian Pepperboard Trade. If interested please call us at +551149912832

These cream colored seeds from the sesame plant are one of the world's oldest spices. Besides their use in baking, they are the source of oil, ground for tahini paste, and used commercially.

Often used in Chinese cuisine to flavor stir-fry and rice dishes, black sesame seeds are also great for encrusting fish and chicken. Use black sesame seeds to add texture.
