Color choices

Impossible triangle illusion beams can begin with teal, blue, and violet across the central shape. Use lighter shades on inner edges and darker tones along outer edges for contrast. Color the surrounding cube frames, diamond loops, and woven knots with orange, yellow, or green, repeating shades where each strip appears to pass over another.

Follow the Woven Paths

Choose a repeating palette for the interlocking strips. Switch shades wherever a beam appears to pass above or below another section.
