yo roomba here!

while i may not be fluent in it i love colour ane shape language, here i tried to do it and ended up with two types, using the shapes in the character vs making the character silhouette mimic the shape, using other shapes to create the target! when it comes to sqaures i think of "strong and sturdy" triangle being "energetic and direct" circle of course "friend" For colours i tend to associate to the base shapes with primary colours like red is sqaure and such seen in the picture
