Seeded random color generator
Seed 2026 always gives #CFD7C2, and its nearest familiar name is silver (#C0C0C0). Give every record, user or build a stable accent color from an ID you already have, without storing a color table. Free in your browser.

This seeded random color generator turns any integer into one stable RGB color. It returns the generated color as a six-digit hexadecimal value and identifies the nearest color in a fixed palette of familiar CSS color names.
Create a color that remains stable
Ordinary random color generation is convenient until a page reloads, a report is rebuilt, or another developer runs the same workflow and receives a different palette. A seed solves that problem by making the apparent randomness reproducible. Enter an integer such as a database identifier, a build number, or a stable index.
The generator mixes that integer into a 32-bit value and takes three bytes for red, green, and blue. There is no clock, browser entropy, hidden state, or external service involved. Consequently, seed 2026 returns exactly the same hexadecimal color whenever it is evaluated.
Store the seed rather than a separately generated color if you want the color to be recoverable from an existing identifier. Negative integers and zero are valid too, while decimal numbers and numeric strings are rejected because they are not integer inputs under this capability's contract.
Understand the hex value and nearest name
The primary result is a standard six-digit RGB hexadecimal value such as #2A7FBC. Its first pair describes red, the second green, and the third blue, with each channel ranging from 00 to FF. The generated value can be used directly in CSS, SVG, canvas drawing, design tokens, or any system that accepts web colors.
The accompanying name is descriptive rather than a replacement for the exact value. The generator compares the new RGB channels with a fixed palette of recognizable CSS named colors, calculates squared Euclidean distance in RGB space, and chooses the closest entry. It also returns the selected named color's own hexadecimal value so you can see what was compared.
Two generated colors may share one nearest name even though their exact hex values differ. For accurate rendering, use the generated hex field; use the name for labels, summaries, accessibility-oriented editorial review, or a human-friendly hint. The fixed palette and alphabetical tie rule keep naming deterministic as well.
Use seeds consistently in applications
Choose a seed from information that is already stable in your application. A numeric record ID works well when each record needs a persistent accent color. Do not use confidential numbers merely to hide them: a color is not encryption, and many seeds can map to the same 24-bit result.
Also avoid assuming that nearby seeds produce nearby colors. The integer mixer deliberately disperses small input changes, so consecutive identifiers tend to land in unrelated parts of RGB space. If you need a harmonious palette, minimum contrast, or restricted brightness, use a dedicated palette or contrast capability after generation.
Keep the returned hex if future algorithm-version independence matters, since beta output formats or mixing details may evolve.
What you can do with it
Stable avatar accents
Derive a repeatable profile accent from an integer account ID without storing a separate random choice.
Persistent chart categories
Assign deterministic colors to numbered categories so rebuilt reports preserve their visual identity.
FAQ
Does the same seed always return the same color?
Yes. The algorithm is pure and has no clock, network, state, or entropy input, so identical integer seeds produce identical results.
Can I use negative seeds or zero?
Yes. Any JavaScript integer value is accepted, including negative integers and zero.
What color does seed 2026 give?
It gives #CFD7C2 every time. The nearest named color is silver, whose own code is #C0C0C0, so the name is a friendly label while the hex code is the exact color.
Do neighboring seeds give similar colors?
No. Each number is deliberately scattered, so consecutive IDs usually land on unrelated colors. That makes it useful for telling records apart, but not for building smooth gradients.
Should I use the hex code or the color name?
Use the hex code to display the color, because it is exact. Use the name for labels, summaries or descriptions; two different generated colors can share the same nearest name.

For developers — API access
Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.
API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

}The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

404 | unknown_type | That task type doesn't exist. |
429 | rate_limited | Too many requests. Use the webhook instead of polling. |
Technical notes
Because the calculation uses only deterministic integer operations, the same seed always produces the same result in the API and browser. It is useful whenever a project needs colors that feel randomly distributed but must remain repeatable across sessions, machines, builds, or collaborators.
Use seeds consistently in applications
When integrating through the API, send the seed as a JSON number without quotation marks. A request costs $0.002; the browser execution uses the same pure solving code, allowing quick checks before automation.
Integration use cases
Reproducible test data
Generate the same visual fixtures on every machine by keeping integer seeds with the test cases.
Technical questions
What happens if the seed is a decimal or string?
The request fails with invalid_input. The seed must be a JSON integer, not a decimal value or quoted numeric text.
Is the returned name the exact generated color?
Usually not. The hex field is exact; name and named_hex identify the closest entry in the capability's fixed named-color palette.
How much does one API request cost?
Each API request costs $0.002. The same deterministic solver can also run in the browser.
