Positive feedback and testimonials are absolutely welcome too. Grateful!
This tool helps you balance contrast (readability) with harmony (how your colors feel together), so your palette is both functional and expressive.
You’ll find details on how to use this tool, as well as insights on contrast and harmony below.
How to Use This Tool
Choosing brand colors isn’t just about what looks pretty, it’s about what actually works in the real world. This tool helps you see how your colors behave together when they’re used for text, buttons, and backgrounds.
Here’s how to think about what you’re seeing as you work through it:
1. What “contrast” actually means
Contrast measures how easily text can be read against a background color.
Low contrast may look soft or aesthetic, but it can quickly become hard to read. This is especially true on mobile devices, in bright light, or for people with visual impairments.
Higher contrast = clearer, more accessible communication.
2. Understanding the standards (AA vs AAA)
You’ll see contrast scores and labels like Pass (AA) or Fail as you review pairings.
- AA is the standard most professional brands aim for. It’s readable, accessible, and realistic for everyday use.
- AAA is more strict and often best reserved for body text in long-form content, but it can be limiting for brand palettes.
This tool defaults to AA because it balances accessibility and design flexibility.
3. Normal text vs large text
Contrast requirements change depending on text size.
- Normal text = body copy, paragraphs, navigation, small labels
- Large text = headlines, big buttons, oversized type 24px+ or ~18+ if bold
Large text can pass contrast at lower ratios because it’s easier to read at scale. That’s why a pairing might fail for body text but still work beautifully for headings.
4. Why some beautiful combinations fail
A failing pairing doesn’t mean the colors are “bad.” It just means they aren’t suited for that specific role together.
Many palettes include:
- colors meant for backgrounds
- colors meant for accents
- colors meant for text
This tool helps you discover how each color wants to be used.
5. Saving favorites
When you check a pairing as a favorite, you’re essentially saying:
“This is an approved, usable combination I feel confident using based on contrast ratios.” You can always uncheck them if you change your mind.
Only favorited pairings appear in your final brand preview and export.
Please note: Favorite pairings can only be saved at Step 2 Contrast Pairings.
6. The final palette preview
The preview at the bottom shows:
- your full palette
- example text and buttons
- your approved color pairings in action
This becomes a visual reference you can screenshot, share, or use when designing your website, graphics, or brand assets.
Please note: Brand colors can only be added or removed at Step 1.
A gentle reminder
Accessibility doesn’t limit creativity — it strengthens it.
When your colors are both expressive and readable, your brand becomes easier to trust, easier to engage with, and easier to remember.
Contrast vs. Color Harmony (Because Yes, You Need Both)
Contrast ensures your colors are readable.
Harmony ensures they feel cohesive.
A palette can technically pass contrast standards and still feel off — too harsh, too busy, or visually exhausting. Harmony is what brings balance.
What makes colors feel harmonious?
Harmony usually comes from a mix of:
- Shared undertones: Colors that lean warm or cool together tend to feel more natural when paired.
- Value balance: Pairing light, medium, and dark colors gives your palette breathing room instead of visual clutter.
- Intentional roles: Not every color needs to do everything. Some are best as backgrounds, some as accents, some as anchors.
- Repetition: When a color shows up in multiple places (even subtly), it creates visual rhythm.
How this tool supports harmony
This tool doesn’t “score” harmony the way it does contrast — because harmony is contextual and intuitive.
Instead, it helps you:
- See all of your colors together at once
- Test how they behave in real UI examples (text, buttons, backgrounds)
- Narrow your palette down to combinations that both work and feel right
When you save favorite pairings, you’re building a usable harmony system, not just a color list.
A helpful way to think about it
If contrast is about clarity, harmony is about comfort.
Great branding needs both.
