What is the weight limit for discs that can be painted any color?

The correct choice indicates that any discs weighing 10 kg or less can be painted in any color. This rule is established to maintain clarity and visibility of the weights being used during competitions, ensuring athletes and officials can easily identify the weights on the bar.

Discs that are typically heavier than this have stricter guidelines governing their appearance to prevent confusion and maintain the uniformity of equipment across competitions. Consequently, the ability for lighter discs (like those at the 5 kg and 10 kg levels) to be in various colors allows for customization while still adhering to the requirements of the International Powerlifting Federation regulations.
