for the colorant i would just ask the workers in the paint area at lowes or home depot for a couple of ounces of colorant of each color you need, bring a couple of dixie cups or foam coffee cups for them to put it in.

But you have to be careful with them. colorant makes a mess and it will stain skin and clothes.

tell them its for your polyurethane and you just are gonna add it in yourself.
i give people colorant for primer all the time where i work.

I made my floats the standard sea glass blue green color.
work in small batches, i used about half a quart of poly mixed with maybe 2 oz of water.
and the colorant is very concentrated so you only need a couple of drops per batch.

also not sure about the color?
test it by brushing it out on any kinda clear plastic, like soda bottles or scrap packaging and if not dark enough you can always build up the layers. Just be sure the first coat is totally dry first.

I had to waste money on stain glass spray paint and that garbage sea glass spray paint till i figured out this method.

good luck!
