Build a Brand Colour Palette from Your Logo or Colour Code

How to Use the Palette Generator Effectively

If you've already run your logo or colour through the tool above, you’ll see a complete palette including supporting colours and neutral tones. What follows explains how the results are structured, how to work with them, and how to make the most of the colour data when applying it to your brand.

This isn’t about theory or colour psychology - it’s a practical guide to working with what you’ve just generated.

What the tool does

You upload a logo file or enter a hex colour. That’s all. From that, the tool creates:

• A primary brand colour

• Five complementary shades designed to work together

• A neutral greyscale set for backgrounds, borders, or text

The results are shown in clear hex format, ready to copy and reuse. Each colour comes with its own label, helping you think in terms of primary tones, accents, and support colours.

There’s no sign-up and nothing to install.

Uploading a logo: what to expect

When a logo is uploaded, the tool analyses the pixels in the image and identifies the most frequent colour value. That becomes your base.

It works best when the logo is simple - flat colours, minimal gradients, and a clean background. If the logo is complex or photo-based, the results may include shades that aren’t meaningful.

Once a base colour is found, the tool builds a palette around it using colour harmony rules. Hue, lightness, and saturation are adjusted to generate options that offer enough contrast without clashing.

You’ll see one main colour, followed by five supporting tones.

Starting with a hex code

If you already have a colour you want to work with, you can skip the image upload and enter it directly.

Hex values should be in the full six-digit format (e.g. #003366). The tool will take that colour as your anchor and create variations using small shifts in tone, contrast, and lightness.

This is useful if your brand already uses a specific colour and you want to build a broader scheme around it.

How it generates variation

The supporting colours are not pulled from a fixed set. Each one is generated based on changes in HSL values and then checked for visual contrast.

The method avoids creating shades that are too similar or overly jarring. Here’s how it typically varies the palette:

• One accent colour with a different hue

• One lighter shade for highlights or backgrounds

• One darker colour for text or buttons

• A blend that sits between your main and supporting tones

The final set usually covers a wide range, while still feeling coherent.

Neutral greys and their use

In addition to the main palette, you’ll get six neutral greys:

• Black (#000000)

• Dark Grey

• Charcoal

• Mid Grey

• Light Grey

• White (#ffffff)

These don’t change based on your input. They’re provided as standard reference tones because they tend to work across most colour schemes.

Designers often rely on neutral colours to reduce visual noise or draw attention to more important elements. Whether you’re building a site, a PDF, or a product UI, having these to hand makes layout work easier.

How to copy and reuse colours

Each colour is presented in a card format with a copy button. You can use these hex codes directly in:

• CSS stylesheets

• Design software (Figma, Photoshop, etc.)

• Presentation slides

• Email templates

• Print design files

There’s no need to convert formats or guess at similar shades.

If the first result doesn’t feel right, you can hit the shuffle button to generate a new set of colours using the same base.

Who it’s for

The tool is designed for people who need to work with brand visuals but don’t want to build a palette manually.

This includes:

• Designers drafting early-stage brand kits

• Web developers creating themes or components

• Marketing teams preparing visual assets

• Freelancers needing fast consistency across touchpoints

• Small businesses who don’t yet have a full set of brand guidelines

You don’t need to be a designer to get something useful from it.

What makes it different

Most palette generators offer static sets or pre-built colour templates. This tool builds colours dynamically from your input. That means the results are more tailored to the brand you're working on, rather than pulled from a fixed list.

The logic behind the palette creation is based on HSL shifts, contrast ratios, and simple blend operations, not templates. It’s designed to be fast, repeatable, and useful without needing expert input.

You can try different logos or colour codes and get a new result each time.

Practical tips

A few things that help when using the tool:

• Use logos with solid fills and clear edges. Avoid noisy backgrounds.

• Stick to six-digit hex codes. Three-digit shorthand isn’t supported.

• If you don’t like the output, try adjusting the base colour slightly or uploading a simpler version of your logo.

• Remember that the neutrals are fixed - you won’t need to regenerate them unless you’re working with a very specific aesthetic.

This isn’t a tool for pixel-perfect design. It’s meant to get you started.

No stored data or logins

Your uploads and inputs aren’t stored or tracked. The colour data is handled in your browser and discarded when you close the tab. If you're working on sensitive client material or branding work-in-progress, you can use the tool without concern.

Summary

This tool helps you generate a full brand palette from either a logo or a single hex colour. It gives you a structured set of colours with contrast, variation, and balance - all formatted for reuse.

The neutral greys are consistent across every result, and there’s no limit to how often you use it.

If you work on websites, content, or branding, it’s worth keeping bookmarked.
