Glass Prism Light Poster - Colorful Rays on Deep Blue

Glass prism light poster turns a bright white beam into a bold fan of saturated color against a deep blue field. The geometric optical illustration pairs crisp forms with luminous, translucent rays. A transparent triangular prism sits near the lower-left center as the beam enters from the upper left and spreads diagonally to the right. Cyan, electric blue, magenta, and yellow bands contrast with generous dark blue space, while reflective glints and a faint halo add luminosity. Physical, unframed print in A5, A4 or A3. Frames and styling accessories shown in mockups are not included.
