Most of the organic textiles we come across for children are neutral or pastel, but if you want to have your colorful, organic cake and eat it, too, you might want to check out Jaya Loves Tekeko.
Vibrant characters (come on, how cute is Professor Acorn?) and motifs adorn their pillows and crib-sized blankets which are made from a blend of organic bamboo and cotton and printed with water-based inks. The pillow inserts are stuffed with a material called kapok which they describe as a light, fluffy hypoallergenic seed harvested in the rainforest. You can see their Jaya Loves Tekeko's goods (they also sell onesies) here.
