Glowing Light Beam with Rainbow Effect

A bright, star-like source radiates a powerful beam of light across a dark background. The light creates a striking visual effect with multiple overlapping, colorful circles, reminiscent of a natural lens flare or a prism dispersing light. The colors visible include shades of blue, green, yellow, orange, and purple, creating a dynamic rainbow appearance. Two subtle horizontal lines, one grey and one blue, are present towards the bottom right.
