A photograph already contains most of the hard work: light, atmosphere and a set of colours that genuinely belong together. Extracting those colours and turning them into a usable palette takes about ten minutes, and it changes how confidently you paint. This is the method to reach for when you are staring at a blank canvas with a reference open beside it and no clear idea where to begin.
It works in any software, from Photoshop and Procreate to Krita, GIMP and free browser tools. The steps stay the same; only the menu names move around.
Choose a reference that does half the work
Not every photo deserves to become a palette. The best references have one clear light source, a limited range of hues and an obvious mood. Fog, overcast days, dusk, lamplight and heavy shadow all compress colour into something you can work with, because they knock out the distracting variety that daylight photographs love to collect.
Be cautious with holiday snapshots taken at noon. A bright street scene can easily contain forty greens, three competing blues and a blown-out white sky, and a palette built from it will feel scattered. Look instead for images with a dominant hue, a single shadow family, and one small area of contrast. If the photo you love is too busy, crop tighter before you start sampling. A section of wall, water or foliage often gives a better palette than the whole frame.
Skip anything with heavy filters or a strong colour cast unless you actually want that cast. You are trying to borrow the light, not the editing.
Clean up the image before you sample
Sampling tools are obedient. They will happily hand you the orange of a traffic cone or the neon of a shop sign, then you will spend the rest of the painting wondering why the palette feels wrong. Spend two minutes tidying first.
- Crop out what you do not want to paint. Cars, signage, bins, stray tourists — if it is not part of the scene in your head, remove it.
- Correct obvious casts. If the whole image leans blue because the camera guessed wrong, nudge it back. You want to sample the hues you intend to paint.
- Reduce the size. A long edge of around 1200 pixels keeps colour-reduction tools fast and stops them latching onto single-pixel noise.
- Clone out small bright distractions if they keep appearing in your swatches. A minute with the healing brush saves an hour of confusion.
Extract the colours
You have two routes: let the software find the palette automatically, or sample it yourself with the eyedropper. Automatic first, then refine by hand.
Photoshop
Duplicate the image, then go to Image > Mode > Indexed Colour and set the number of colours to somewhere between 8 and 16. The image will posterise into flat blocks of colour. Open Image > Mode > Colour Table and you have your palette, which you can save as a swatch file and load into the Swatches panel.
Procreate, Krita and GIMP
All three can build a palette from an image rather than from individual taps of the eyedropper. In Procreate, the palette panel lets you create a new set from an imported image. GIMP's palette dialogue can import colours from a picture, and Krita's palette docker accepts colour sets you save. The workflow is the same in each case: bring the photo in, generate the set, then edit it.
Manual sampling, which is often better
Once you have a rough set, sample deliberately rather than randomly. Do this:
- Apply a mosaic or pixelate filter at a large block size so each area becomes one average colour.
- Pick the sky or main light area, then the mid-tones, then the deepest shadow. Three swatches minimum.
- Add one accent — the smallest, most saturated colour in the scene.
- Delete every swatch you cannot imagine using. Aim for eight to twelve.
- Save the set with a descriptive name, such as harbour-dusk or rainy-market.
Eight swatches you actually use will carry a painting further than forty you keep scrolling past.
Reduce the set and give every colour a job
A palette is not a collection, it is a team. Assign roles before you paint and the decisions become much quicker.
- Base or mid-tone: the colour that covers most of the canvas. Usually the least saturated swatch.
- Shadow: a darker, cooler or more muted version of the base. Resist the urge to reach for black.
- Light: a lighter, warmer or cleaner step up. Keep it for a small area.
- Accent: the one saturated colour that draws the eye. Use it sparingly.
- Neutral: a grey or earth tone for breathing space and for mixing in between.
If two swatches sit almost on top of each other, delete one. Duplicates make you hesitate, and hesitation in the middle of a painting is expensive.
Check values, then test the palette properly
Turn your swatches into greyscale and look at them in a row. You want clear, roughly even steps between the lightest and darkest, not six colours clustered in the middle. A palette with good hue variety but flat values will produce a muddy painting no matter how carefully you mix.
Then run a fifteen-minute thumbnail. Block in your composition with the palette only, and do not allow yourself to sample anything new from the photo. If the thumbnail reads clearly at postage-stamp size, the palette works. If it goes grey and shapeless, your values need attention; if it looks garish, your accents are too large or too many.
Keep the thumbnail. It is a free rehearsal, and it tells you what to fix before the real painting begins.
Build a palette library you will actually use
Save every palette you like as a reusable swatch file — .ASE, .ACT, .PAL and Procreate's own format all load quickly — and name them by subject and light rather than by date. Coastal-morning tells you something in three months; untitled-4 tells you nothing.
Group them into a folder by mood: warm interiors, overcast landscapes, night city, forest. After a year you will have a personal library built from photographs you chose for a reason, and starting a new piece becomes a matter of picking a mood instead of hunting for a reference. Finish each session by deleting the swatches you never touched. A palette that stays lean stays useful.
