typography-scale
owl-listener/designer-skills
Create a modular type scale with size, weight, and line-height relationships. Use when establishing typographic structure. For line length only use readable-measure; for judging type on an existing screen use critique-typography (visual-critique).
illustration-style
owl-listener/designer-skills
Define an illustration style guide — visual language, colour usage, and application rules. Use when commissioning or standardising illustration. For icons, use icon-system (design-systems).
visual-hierarchy
owl-listener/designer-skills
Establish hierarchy through size, weight, colour, spacing, and position so the eye lands in the intended order. Use when composing new work. For judging an existing screen, use critique-visual-hierarchy (visual-critique).
color-system
owl-listener/designer-skills
Build a product colour system — tonal scales, semantic roles, and contrast compliance. Use when defining or rebuilding colour from scratch. For dark-mode adaptation use dark-mode-design; for chart palettes use data-visualization; for multi-brand token architecture use theming-system (design-systems).
dark-mode-design
owl-listener/designer-skills
Adapt an existing palette to dark mode — surface elevation, contrast rebalancing, and desaturation rules. Use when you already have a light palette to translate. For building the base palette first, use color-system.
