16 colored plain transparent blocks

I think it would be great if we had a new type of block that would be transparent and coming in 16 color variations, and most importantly, plain like concrete.

It would be a purer alternative to glass, without the edges and “reflections” that we have in its texture. It could also be used to craft new types of panes.

Where do these transparent colored blocks would come from? They could be “clear glass” or “pure crystal”, obtained by smelting row crystal obtained in crystal caves for example. But this is secondary and I don’t care if Mojang finds another way to include them! I want this post to be about the general idea and not to be too much specific.
