Would this be competition legal;

No... No transparent cube is competition legal, because it allows you to see more pieces than on the original. This violates the modification rule in the regulations.

Aw..thats a bummer, I mean in the picture you can't even make out what color is behind it!

 

[adragast]

No but you can guess that the bottom color is blue / black or at least dark.

Hi

I guess it would be up to the main judge to examine the cube in question and evaluate if there is any extra benefit with the cube. In short he would decide if the mentioned rule applies. Transparency is not mentioned specifically in the rules (except the part about more visible parts/colours). Transparency does not automatically give this benefit, so an inspection would be required IMHO

lol

If the basis of the rule is that you can see the color of the stickers on faces that you normally wouldn't see then why can't you use stickers that have a "white backing" on such a cube?

It's kind of beyond me as to how someone can use color recognition on all sides of the cube. You typically only need to see three faces to know the orientation of all the cubies

Easier PLL recognition, the same thing goes for thick tiles, you can see the colour over the edge.

Because of that rule I cannot use my favorite Pyraminx in competiton but I have no benefit of the thicker tiles at all

Ron specficially forbids it here.

He said "Therefore these specific transparent cubes cannot be used in official WCA competitions.". So there's nothing wrong with transparency; some different transparent cubes could be legal.

Don't bother trying to use them. Just use a normal cube.
