Carlos Posts: 11 Country : France	Carlos posted @ 2026-04-25 1:01 PM The four given '4's' can be colored. These clues only refer to the numbers options, not to the paint options. (Interestingly, it seems there is no good way to indicate clues referring to white painting for this puzzle.) Edited by Carlos 2026-04-25 1:02 PM
