About the Color Palette Generator API

Color Palette works by generating color palettes based on color theory principles. It returns harmonious colors with multiple format outputs (HEX, RGB, HSL), accessibility metrics, ready-to-use CSS variables, and downloadable palette images.

What people use it for

Graphic Design: Use the Color Palette API to generate color palettes for graphic design projects. Use the data to create visually appealing designs, logos, and illustrations
Web Development: Develop websites by using the Color Palette API to generate color palettes. Get ready-to-use CSS variables and ensure WCAG accessibility compliance
UI/UX Design: Design user interfaces by using the Color Palette API to generate color palettes. Use accessibility data to ensure text readability and contrast compliance
Brand Identity: Create cohesive brand color systems with harmonious palettes. Export as CSS variables for consistent implementation across platforms

Ways to call it

Common questions about the Color Palette Generator API.

Read the docs →

What does the Color Palette Generator API do?

Color Palette is a powerful tool for generating harmonious color palettes. Generate color schemes (mono, contrast, triade, tetrade, analogic) with accessibility data, CSS exports, and palette images.

How do I authenticate Color Palette Generator API requests?

Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.

How much does the Color Palette Generator API cost?

Each call spends 2 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the Color Palette Generator API?

Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.

What response formats does the Color Palette Generator API support?

JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.

What HTTP method does the Color Palette Generator API use?

GET over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.

Request parameters — GET /v1/colorpalette

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`color`Required	string	`FF5733`	The base color to generate the palette from (HEX format without #) hexColor

Optional

Parameter	Type	Example	Description
`scheme`Optional	string	`triade`	The color scheme type `monocontrasttriadetetradeanalogic` default triade
`variation`Optional	string	`soft`	The color variation `defaultsoftpastellighthardpale` default default
`count`OptionalPremium	integer	`5`	Number of colors to return (1-16). Free tier limited to 5 colors default 5 · range 1-16
`distance`OptionalPremium	number	`0.5`	Color spacing distance (0-1). Affects triade, tetrade, and analogic schemes default 0.5 · range 0-1
`addComplement`OptionalPremium	boolean	`true`	Add complement color to analogic scheme default false
`webSafe`Optional	boolean	`false`	Return web-safe colors only default false

Example request

curl "https://api.apiverve.com/v1/colorpalette?color=FF5733&scheme=triade&variation=soft&count=5&distance=0.5&addComplement=true&webSafe=false" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — GET /v1/colorpalette

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	Color Palette Generator calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
