Extract a colour palette from an image or video frame
Cromoteca reads the dominant colours out of a still or a frame of video and gives you hex codes you can paste straight into a design tool, with the proportion each colour occupies.
What you get
A ranked palette with hex values and the share of the frame each colour covers, so you can tell a true dominant from an accent that merely stands out. Copy the whole set in one action rather than sampling swatches by eye.
Frames, not just stills
Because Cromoteca already handles video, you can pull a palette from a specific moment in a downloaded clip — the grade of a particular shot rather than a thumbnail that may have been compressed or re-coloured.
Read locally
Colour extraction runs on your machine. The image is not uploaded to a service, not stored, and not used for anything else. This matters for unreleased work, client material, and anything under embargo.
Limitations
Heavily compressed sources can shift colour, and a palette from a screenshot reflects the screenshot, not the original grade. For accurate colour work, sample the highest-quality version you have rather than a re-uploaded copy.

FAQ
FAQ
Is the image uploaded anywhere?
No. Colour extraction happens on your own machine. The image is not sent to a server and is not retained.
Why do colours differ from the original?
Compression and re-encoding shift colour, sometimes noticeably. A palette taken from a re-uploaded or screenshotted copy reflects that copy. Use the highest-quality source you have.
Can I pull a palette from a specific video frame?
Yes. Because Cromoteca downloads and handles the video itself, you can extract from the exact moment you care about rather than a platform thumbnail.
