Color Mixer Online: Mix Colors Like Real Paint and Get the Exact Recipe
Are you looking for a color mixer online that behaves like real paint? Do you see a shade in a photo and then waste half an hour guessing how to mix it? You are in the right place, my friend. In this guide we will learn how this color mixer works, step by step.
Let's not waste your time and go straight to the point. Most tools give you a code like #3A7CA5 and stop there. This online color mixer goes one step further and tells you which real pigments to squeeze out of the tube, and how much of each.
What is this online color mixer?
This color mixer from imagetocolor.com is free and runs in your browser. You can mix colors online by tapping pigments, or you can pick a color from a photo, type a HEX code, or use the eyedropper. The tool then calculates a recipe using real artist pigments such as Titanium White, Ultramarine, and Cadmium Red.
It is more than a simple color blender for screen colors. It simulates how paint behaves, using a spectral model based on the Kubelka-Munk theory. Why does this matter? Because blue and yellow paint make green, but blue and yellow light do not. Normal RGB mixing gets this wrong, and color mixing online with spectral data gets it right.
The tool is completely free, needs no account, and your photo never leaves your device. It works on phones, tablets, and computers. Whether you search for a color mixer or a colour mixer, the goal is the same: no more guessing.
How to use the tool step by step
Option 1: Match a color from a photo
- Open the Match tab.
- Under Pick from a photo, tap Choose photo, drop an image, or paste it with Ctrl+V. On a phone you can tap Take photo.
- Tap any spot on the picture. A small ring shows the exact point you picked.
- Look at the result card. You will see your target on one side, your mix on the other, and the match score.
- Read the recipe below it. Every pigment shows its percentage and its amount in ml.
Option 2: Match a HEX code
- Type your code in the Target colour box, or open the built-in color picker and choose any shade by hand.
- Choose the maximum number of pigments. Three is a good start, because fewer paints usually means cleaner colors.
- Press Match colour.
Option 3: Mix colors by hand
Tap any bottle in the Pigments list to add one part to the dish. Tap again to add more. This is how you mix colors online the same way you would on a real palette. The dish swirls, and the name, HEX, RGB, and HSL update live. Drag your finger or mouse over the dish to stir with the palette knife.
Features of the tool
Recipe tab
Shows percentages, a color bar, and a slider for each pigment. You can copy the recipe, share a link, and see shades and tints of your mix. It also warns you if a pigment can fade in daylight.
Match tab
This is the heart of the color mixer. The solver tries thousands of combinations and gives you the closest one. The score uses CIEDE2000, the same color difference formula used in professional color work. A score above 85% is an excellent match, and most people cannot see the difference.
Lab tab
Here you check harmonies, compare daylight with incandescent light, see the difference between wet and dry acrylic, and test how a glaze looks over white, black, grey, or a toned ground. You also get the full reflectance spectrum.
Palette tab
Tick the paints you actually own and switch on Mix only from my palette. If the match is weak, the tool tells you which single tube would improve it the most. This saves real money.
Chart tab
A grid of every two-paint combination from your palette, at the ratio you choose. It is the fastest way to learn what your paints do together.
Saved tab
Keep your favorite mixes and copy them as CSS variables. Everything is stored on your device.
Paint kit builder
Upload a photo and build a kit of 4, 6, or 8 colors. The tool finds the main colors in the picture and gives a recipe for each one. It is great for landscape and portrait studies.
Why this tool is important
Mixing by eye is slow, and it wastes paint. When you mix color online first, you can test an idea without losing a drop. Beginners often add the dark color too fast, then add more white, then more color, and end up with a huge pile of mud. A recipe removes the guessing.
It also helps teachers, students, hobby painters, model makers, and anyone who needs to repeat the same color later. Write the recipe once, and you can mix the same color next month. From my personal point of view, repeatability is the biggest benefit.
How it compares with other color mixing tools
There are many good color tools, and each one has its place. Most people who search for a color blender land on tools that only blend screen colors. The tools below are different, because they simulate real paint. I reviewed the public pages of two of the strongest ones, Trycolors and PaintMaker, in October 2026. Features and prices change, so check each site before you decide.
| Feature | This color mixer | Trycolors | PaintMaker | Typical image color pickers |
|---|---|---|---|---|
| Pick a color from a photo | Yes | Yes | Yes | Yes |
| Recipe with real pigments | Yes | Yes | Yes | No |
| Kubelka-Munk paint mixing | Yes | Yes, in PRO mode | Yes | No |
| Mix only from paints you own | Yes | Yes | Yes, for members | No |
| Named brand paint libraries | No, generic artist pigments | Yes, 250+ brands | Yes, about 24 paint sets | No |
| Access | Free, no sign-up | Free to try without registration, paid plans exist | Free account, recipes use credits | Mostly free |
| Chart of every two-paint mix | Yes | Yes | Not seen | No |
| Lighting, wet/dry and glaze tests | Yes | Not seen | Daylight and adaptation settings | No |
| Extras | Paint kit from one photo, saved mixes, harmonies | Paint by numbers, games, challenges, API | Image splitting, projector view, printable palette | Usually none |
Let's be honest here. If you need a recipe for one exact brand, such as a particular tube of Golden or Winsor & Newton, Trycolors and PaintMaker have measured libraries that this tool does not have. Both are excellent for that job.
This color mixer has a different strength. It is completely free with no account, it keeps your photo on your device, and it gives you the Lab tests and the match score in one clean page. From my personal point of view, the best choice is to use this tool for fast, private experiments and a brand-specific tool when you need a recipe for one product line.
If you only need a HEX code for a website, any simple picker will do the job. If you hold a brush, a paint-based color mixer online is the tool built for you.
Drawbacks you should know
Pros
- Real pigment recipes, not guesses
- Free, private, and fast
- Works on every screen size
- Honest score for every match
Cons
- Pigment data are good estimates, so brands differ slightly
- Screens cannot show every paint color, such as very bright neons
- Phone photos change with lighting
Always do a small test swatch before you mix a big batch. Unfortunately no calculator can replace this step.
Frequently asked questions
Can I mix colors online for free?

Is the tool really free?
Yes, it is free to use as much as you like, and there is no sign-up.
Is my photo uploaded to a server?
No. The photo is read inside your browser and stays on your device.
Why is my match below 100%?
Some colors cannot be made from your selected pigments. Raise the pigment limit, or add a tube from the suggestion shown under the result.
Does it work for oil, acrylic, and gouache?
The pigments are the same. The tool is closest to opaque and semi-opaque paint, and the Lab tab gives an estimate of how acrylic shifts when it dries.
What does ΔE mean?
It is the distance between two colors. Under 1 is invisible, under 2.5 is excellent, and under 5 is close.
Conclusion:
This color mixer combines a photo color picker, a physically based color mixer online, and a set of studio tests in one clean page. It saves time and paint, and it teaches you how colors really behave. Start with three pigments, check the score, and make a test swatch.
