I built a brand extension kit on a placeholder apparel identity. The given wordmark, three colors and serif stay unchanged; each color becomes step 500 of a nine-step scale generated from its own hue, for 28 colors, all checked warm. A two-family type system, wordmark and monogram lockups with clear space and minimum sizes, and four direction rules for elevated, warm, editorial and fashion-forward. Seven pieces are set as SVG files: social 4:5, 9:16 and 1:1, an email header and product block at 2x, and a 6×9 in mailer and 4×6 in insert at 300 PPI with 0.125 in bleed. Headless Chromium measured every text run in every file against its safe area (closest 7 px inside). Every piece uses at most four palette colors and two type families, serif headlines at least three times the smallest text, and text contrast of at least 4.5:1. Each piece has a template spec of locked and editable layers with character limits for the Canva build, plus photo direction per format.
