Geometric Alphabet Color Accents

A clean, high-resolution typography specimen sheet displaying the complete uppercase English alphabet from A to Z. The layout is arranged in four horizontal rows on a plain white background: the first row contains letters A through G, the second row H through N, the third row O through U, and the fourth row V through Z. Each letter is rendered in a bold, black, geometric sans-serif font characterized by sharp angles and chamfered corners. A distinctive design feature is present on every character: a single small, solid-colored square or rectangular accent block placed at a specific vertex or terminal point of the stroke. These accents vary in color across the alphabet, including shades of red, orange, yellow, green, cyan, blue, purple, and magenta. For example, the 'A' has a red accent at its apex, the 'B' has an orange accent on its lower curve, and the 'X' features an orange accent at its central intersection. The overall aesthetic is modern, minimalist, and graphic, resembling a custom font showcase.
