Design Process for Sahaj
When designing for Sahaj:
-
Understand the Brief — What's being designed? Who's the audience? What's the goal?
-
Choose Primary Color — Start with Indigo #33357D
- Use for hero sections, main backgrounds, primary CTAs
- If Indigo doesn't fit, use Navy as secondary fallback
-
Add Supporting Elements

- Shapes/Graphics palette for illustrations and accents

-
Reference Logo Standards
- Never recreate—use official files only
- Maintain clearspace (1/4 logo height)
- Never rotate, distort, or apply effects
-
Validate Against Standards
- ⚠️ CHECK CONTRAST RATIOS — Ensure 4.5:1 for body text, 3:1 for large text

- Verify typography uses correct weights and sizes
- Ensure logo treatment follows guidelines
- Confirm shapes are from official library
-
Deliver
- Provide clean files and specifications
- Document color choices and rationale
- Include font usage instructions
- Verify accessibility before shipping

- Logo never changes — Use official files, maintain clearspace
- Shapes are from library — Don't create new shapes
- Colors are from palette — Don't invent new colors
