The scene shows a color_cycle sequence. Elements are arranged horizontally from left to right. The last position contains a question mark (?) indicating a missing element. Observe the pattern: the colors follow a cyclic order that repeats after a certain number of elements. Determine the element that should replace the question mark to complete the sequence according to the established pattern. Only modify what the task requires; keep the background and any other element unchanged. Output 1 image showing the final result.
