MarkerBoard Skill

Create bold marker-art infographics on dark blackboard backgrounds. Professional art marker aesthetic — thick, saturated, confident strokes with vibrant pigment colors on dark surfaces.

Core Aesthetic

The MarkerBoard Style:

• Background: Deep matte BLACK (#0A0A0A) — like a premium blackboard
• Line Style: Bold art marker strokes — thick, saturated, confident. Slightly bleeding edges where ink meets surface. NOT chalk (no dusty/wispy texture)
• Colors: Vibrant marker pigments on black (Electric Blue #2D9CDB, Signal Red #EB5757, Lime Green #6FCF97, Warm Amber #F2994A, Violet #BB6BD9)
• Typography: Bold hand-lettered marker style — thick strokes, confident, slightly uneven baseline
• Icons: Bold line drawings with filled marker strokes, simple but punchy shapes
• Composition: Educational panels, comparison layouts, concept diagrams
• Feel: Like someone took a set of premium Copic markers to a blackboard — professional, bold, vibrant

ALL GENERATED IMAGES GO TO ~/Downloads/ FIRST

Workflow Routing

Route to the appropriate workflow based on the request:

• Comparison (X vs Y, before/after) → Workflows/Comparison.md
• Concept explanation → Workflows/Concept.md
• Process or steps → Workflows/Process.md
• Business/strategy visual → Workflows/Business.md
• General/flexible → Workflows/General.md

Color Palette

Color Rules:

• 60% warm white marker strokes for primary content
• 40% vibrant marker colors (use 2-3 colors max per image)
• Colors should look like saturated marker pigment — rich and bold
• Never use all colors in one image — select 2-3 accent colors per composition

Typography Style

Bold marker lettering — NOT thin chalk, NOT formal fonts:

• Headers: Large, thick marker strokes, slightly uneven but confident
• Labels: Medium weight, clear and legible marker hand-lettering
• Annotations: Smaller but still bold marker, personal voice

All text should look like someone wrote it with thick art markers on a blackboard.

Icon & Figure Style

Bold marker drawings:

• Simple figures with thick marker outlines (not stick figures — slightly more substance)
• Filled shapes with marker color — solid blocks of pigment
• Basic but punchy icons (bold strokes, filled elements)
• Slightly imperfect lines — hand-drawn but confident, NOT wobbly/tentative
• Some marker bleed/overlap where colors meet — adds authenticity
