One-Answer WCA Competition and Regulations Question Thread

I’m sure it’s been asked before but it’s been a long day and I’m feeling lazy...Are there any restrictions on color shades or schemes for WCA competitions?

Can I use a black side opposite yellow?

Which regulation addresses this?

The only regulations on color shades indicate that they need to be distinguishable:
3d2) The colors of the colored parts must be solid, with one uniform color per face. Each color must be clearly distinct from the other colors.

Yes, you are allowed to have Black opposite yellow, and there are several people that use that, especially with Square 1.

Here is the regulation section that address the color schemes for your cubes:
Article 3: Puzzles
  • 3a) Competitors must provide their own puzzles for the competition.
    • 3a1) Competitors must be ready to submit their puzzles when they are called (see Regulation 2u).
    • 3a2) Puzzles must be fully operational, such that normal scrambling is possible.
    • 3a3) Polyhedral puzzles must use a color scheme with one unique color per face in the solved state. Each puzzle variation must have moves, states, and solutions functionally identical to the original puzzle.
    • 3a4) Puzzles must not have electronic components (e.g. Bluetooth or Wi-Fi capabilities, motors, sensors, lights). See Regulation 2i.
  • 3d) Puzzles must have colored parts, which define the color scheme of the puzzle and must be one and only one of the following: colored stickers, colored tiles, colored plastic, or painted/printed colors. All colored parts of a puzzle must be made of a similar material.
    • 3d1) For competitors with a medically documented visual disability, the following exceptions apply:
      • 3d1a) Blind competitors may use textured puzzles with different textures on different faces. Each face should have a distinct color, to aid in scrambling and judging.
      • 3d1b) Color blind competitors who cannot distinguish between the necessary number of colors may use colored parts with patterns, if it has been explicitly approved according to Regulation 2s. Patterns may come from stickers or be drawn.
    • 3d2) The colors of the colored parts must be solid, with one uniform color per face. Each color must be clearly distinct from the other colors.
  • 3h) Modifications that enhance the basic concept of a puzzle are not permitted. Modified versions of puzzles are permitted only if the modification does not make any additional information available to the competitor (e.g. orientation or identity of pieces), compared to an unmodified version of the same puzzle.
    • 3h1) "Pillowed" puzzles are permitted.
    • 3h2) Puzzles whose colored plastic is visible inside the puzzle (e.g. "stickerless" puzzles) are permitted. This does not include the following puzzles:
      • 3h2a) Puzzles with transparent parts that can reveal more information about the state of the puzzle. Exception: An overlay sticker or a logo (see Regulation 3l).
    • 3h3) Any modifications to a puzzle that result in poor performance by a competitor are not grounds for additional attempts.
    • 3h4) For Clock, custom "inserts" (the same shape and size as the traditional paper inserts) are permitted, at the discretion of the WCA Delegate. The inserts must have a clear indication of 12 o'clock that matches the original inserts.
  • 3j) Puzzles must be clean, and must not have any markings, elevated pieces, damage, or other differences that significantly distinguish any piece from a similar piece. Exception: a logo (see Regulation 3l).
    • 3j1) Puzzles are permitted to have reasonable wear, at the discretion of the WCA Delegate.
    • 3j2) Definition: Two pieces are similar to each other if they are identical in shape and size, or mirrored in shape and identical in size.
    • 3j3) Corrugated/textured parts which permit the orientation of pieces to be distinguished by feel are not permitted for blindfolded events.
  • 3k) Puzzles should be approved by the WCA Delegate before use in the competition.
    • 3k1) If a non-permitted puzzle is found during a round, the competitor must not continue to use the puzzle, and must submit a replacement.
    • 3k2) Penalty for attempts done with puzzles which are not permitted: disqualification of the attempt (DNF). The following exceptions apply:
      • 3k2a) If a non-permitted puzzle is found before a round is complete, affected results in the round may be replaced with extra attempts, at the discretion of the WCA Delegate.
      • 3k2b) 3x3x3 Multi-Blind: if any puzzles are found to be non-permitted, such puzzles may be individually counted as unsolved (without disqualifying the entire attempt), at the discretion of the WCA Delegate.
  • 3l) A puzzle may have a logo on a colored part. If it does, it must have at most one colored part with a logo. Exception: For blindfolded events, a puzzle must not have a logo.
    • 3l1) The logo must be placed on a center piece. Exceptions for puzzles that do not have center pieces:
      • 3l1a) For Pyraminx and 2x2x2, the logo may be on any piece.
      • 3l1b) For Square-1, the logo must be on a piece in the equatorial slice.
    • 3l2) The logo may be embossed, engraved, or consist of an overlay sticker.
  • 3m) All brands of puzzles and puzzle parts are permitted, as long as the puzzles comply with all WCA Regulations.

Thanks for the prompt replies. Cheers,
 
Would it be legal to take the face off of Rubiks clock (just the clear part) and put it on a Lingao? The reason being is that my Lingao is better than my Rubiks, but the Lingao's face is cracked, making it illegal. I don't see any reason why it wouldn't be. People use yuxin 5x5 springs in other cubes. Thanks!

Changing the case on your clock shouldn't interfere with its legality.
 
Can you switch mains half way during a round?
e.g, after I finish solve no.2, I hand in a different cube to use for the next solve(s) in the average.
 
So, I recently have been messing with the valk elite's magnets as I have found the red magnets I've been using a bit too stable and the clear a bit too unstable. So I came across the discovery that I could put 3 clear in and 3 red in, and as long as one red was opposite one clear it would make a consistent magnetic feel across the whole cube. However then the question is is this legal? I wouldn't see why not since it's a consistent feel and you can't detect any visual difference unless you take the cube apart. So if someone could clear this up that would be great :)
 
As far as I can tell, it should be legal. I could be wrong though, it might be good to have a WCA Delegate give their thoughts, as most rules involve delegate discretion.

If you have different magnet strength on one side you could feel that that side is different from the rest, so for blind solving I wouldn't allow it.

With the Valk Elite's interchangeable centre magnets, the pull will be the same for all of the faces if you mix magnet strengths in the way u Cube was asking about.

You do have a point that it's theoretically possible to feel a difference in magnet strength between the centres and edges, but (imo) the difference is too small to detect compared to the corner-edge magnets. Or at least, I can't do it… which doesn't rule out the possibility that people with more sensitive hands might be able to.
