Alphabet of colorful geometric lowercase letters

A vibrant graphic display of the lowercase alphabet arranged on a stark black background. Each letter is composed of bold, geometric sections with a facet-like design, utilizing a bright primary and secondary color palette. The letters through are uniformly sized and aligned in a grid pattern. The style is modern, minimalist, and playful, reminiscent of high-end corporate identity design or contemporary poster art. The light sources seem to interact with each segment of the letters to create a subtle 3D prismatic effect, making them pop against the void. The composition is balanced and clean, with each character showcasing a unique combination of colors such as vibrant reds, oranges, blues, greens, and purples, all rendered in a flat, vector-like aesthetic.
