I have made a few , the only choice I give the recipient is - Pastels , brights, or primary colors. Almost all come back with requests for pastels. Most pick based on a color(s) used in the babies room. Only once about a year ago , the recipient painted the babies room mocha!
Those I have sold at shows , have all been pastels, purchased typically by the grandmother.
Those that I have done for ages 4 and up .. thats a different story ... its all brights... and if its for a girl ... it needs purple!
