Color Tools
Color Tools work on particular colors rather than the overall look. Some change pixels, such as swapping one color for another or keeping a single color. Some read colors out of a picture. Two are plain number converters between screen RGB and print CMYK.

Color Changer recolors a whole image in the hue and saturation of a color you pick, keeping each pixel's light and shade. Free, no signup, no upload.
Open toolColor Replacer recolors pixels close to one color with another and keeps their shading. Set tolerance, preview, save a PNG. Free, no signup, no upload.
Open toolColor Editor swaps the hue of every pixel for one theme color and keeps its saturation and lightness, so grays stay gray. Save a PNG. Free, no signup.
Open toolPalette Extractor finds the 8 most common colors in an image and saves them as a swatch PNG labeled with hex codes. Free, no signup, no upload.
Open toolDominant Colors counts the colors in a photo and lists the top 8 as hex codes with the share of the image each covers. Free, no signup, no upload.
Open toolSelective Color fades everything except one chosen color toward gray for a color-splash look. Set tolerance, save a PNG. Free, no signup, no upload.
Open toolExtract Channel turns the red, green, blue, or alpha channel of an image into a grayscale picture you can inspect or reuse. Free, no signup, no upload.
Open toolCMYK to RGB converts cyan, magenta, yellow, and black percentages into RGB values and a hex code as you type. Simple uncalibrated formula. Free, no signup.
Open toolRGB to CMYK turns red, green, and blue values from 0 to 255 into cyan, magenta, yellow, and black percentages plus the hex code. Free, no signup, no upload.
Open toolSolid Color makes a PNG filled with one color at any size from 16 to 8000 pixels per side. Pick the color, type the size, download. Free, no signup, no upload.

- Color Replacer: Swaps one color you pick for another. Tolerance, from 0 to 100%, decides how close a shade must be to count, so raise it to catch the shadowed folds of a colored shirt.
- Selective Color: Keeps the color you pick and fades the rest toward gray: the red umbrella on a gray street look.
- Color Changer: Blends the whole picture toward one color at the strength you set. Color Editor applies the same blend. If only one color should change, use Color Replacer.
- Palette Extractor: Lists up to eight colors as hex codes with how many sampled pixels each covers. Dominant Colors gives the same list, so either works for picking theme colors.
- Extract Channel: Shows the red, green, blue, or alpha channel as a grayscale image. The alpha view is a quick check of a cutout's transparency.
- RGB to CMYK: Turns 0 to 255 RGB values into CMYK percentages plus a hex code. CMYK to RGB goes the other way.
- Solid Color: Makes a plain one-color PNG at an exact size, for a background, a swatch, or a stand-in image.
