A look at all the castings made in order from left to right. (The leftmost being the first casting). I initially favored the blue coloring, as I thought it would be nice for the umbrella. I actually poured blue dye into my first cast but it was not enough. By the time I got to my third or fourth mold, there was no blue left so I switched colors. I had anticipated the bright pink one (the second to last) to turn out red, and when it did not I put much less dye in for my last casting.
