Color Wheel Spinner — A Random Color Picker for Designers and Artists
Stuck reaching for the same five colors? Spin the wheel and let it hand you a hue you'd never have picked on purpose. Cryptographically random, works offline, no signup.
From mood boards to bedroom walls — a faster way out of color paralysis
为什么选择wheel.expert？
Break Your Color Habit
Everyone has a default palette they keep returning to. The wheel doesn't. It pulls colors at random, so you land on pairings your eye usually skips — and that's often where the interesting work starts.
Runs in the Studio, Offline
Patchy WiFi in the back of the art room? It still works. As an installable web app the wheel spins with no connection at all — at a desk, a classroom, or a craft-fair table.
Add Your Own Hex Codes
Brand colors, a client's palette, or just the six tubes of paint actually in your drawer — type them in. The wheel spins only what you load, not a generic rainbow.
Settle It at the Paint Counter
It loads fast and works by touch, so a 'sage or olive?' standoff can end right there in the hardware-store aisle instead of three weeks later.
Every Color, Equal Odds
Some pickers quietly lean toward certain values. This one draws from the Web Crypto API — the randomness browsers trust for security — so a pale buttercream and a deep navy have exactly the same chance.
Free, No Account
Nothing is paywalled, nothing is emailed to you, nothing is stored. Open it, spin it, close the tab.
How to Use the Color Wheel
Load Your Colors
Start from the preset spread of reds, blues and greens, or wipe it and type your own. Plain names like 'Burnt Orange' and hex codes like #2E8B57 both work.
Make It Yours
Add as many swatches as you want, rename them, reorder them. A ten-color wheel feels nothing like a two-color one, so tune it to the decision in front of you.
Spin
Tap the center. The wheel turns, slows, and settles on one color — chosen by the algorithm, not by where you 'happened' to stop it.
Use It, or Build a Palette
Take the result and go. Or remove it and spin again for a second and third color until you've got a whole scheme. Past picks wait in the history panel.
What People Actually Use the Color Wheel For
Beating the Blank Canvas
Illustrators spin for a starting hue when nothing feels right. One random anchor color is often enough to break the stall and get the first mark down.
Choosing Paint Without the Month-Long Debate
Load the shortlist of swatches you can't decide between and let the wheel break the tie. No more six samples taped to the wall gathering dust.
Outfit and Wardrobe Colors
Pull the colors you actually own, spin, and build the day's outfit around whatever lands. It's a small game that makes getting dressed a little less automatic.
Party and Event Themes
Planning a birthday, a shower, a wedding? Spin a primary theme color, then a secondary, and you've got a scheme to run invites, balloons and table settings off of.
Art-Class Warm-Ups
Teachers spin a color to set the day's sketch constraint — 'everything you draw today lives in this hue.' Limits like that nudge students past their comfort colors.

真正随机选择 - 我们的算法如何工作
与许多使用Math.random()的转盘不同，wheel.expert使用Web Crypto API（crypto.getRandomValues()）进行加密安全的随机数生成。这与密码生成器等安全关键应用程序使用的API相同。
网络加密 API (CSPRNG)
我们使用crypto.getRandomValues()，这是所有现代浏览器内置的加密安全伪随机数生成器（CSPRNG）。
无偏选择算法
当所有条目具有相同的权重时，我们使用拒绝抽样来消除模块偏差 - 随机选择中的常见问题。这确保了每个条目都有数学上相同被选中的机会。对于加权条目，概率与指定的权重成正比。
客户端透明性
所有随机选择均在旋转时在您的浏览器中发生。该代码是开放的，可以通过浏览器的开发工具进行检查。对于大额赠品，我们建议旋转过程中进行屏幕录制，以证明对观众的公平性。
🔍 亲自验证： 打开 DevTools (F12) 并在控制台中检查我们的随机数生成。我们使用 window.crypto.getRandomValues() - 与银行和安全应用程序使用的加密 API 相同。

常见问题
Yes. Clear the presets and type any color name or hex value — #FF6B35, 'Tiffany Blue', whatever you work with. The wheel only spins the colors you load, so a brand palette stays on brand.
It's genuinely random. The picker draws from the Web Crypto API, the same source browsers use for security keys, so a pale yellow has the same odds as a deep navy. There's no hidden weighting.
Spin once, hit 'remove winner,' and spin again. Each pick drops out of the next round, so three or four spins give you a clean multi-color palette with no repeats.
It does. The color wheel installs as a progressive web app, so once you've opened it the first time it runs offline — handy in a studio, a classroom, or the far corner of a craft fair.
Plenty of art teachers do. Project it, spin a 'color of the day,' and set it as the lesson's constraint. It turns an abstract idea — working outside your default hues — into a quick daily exercise.
Then load just those. A two- or three-color wheel works fine, and the slow wind-down still makes the reveal feel like a real decision rather than a coin you flipped in your head.
