HSL Mode · Texture Preservation · Multi-rule — No Upload, Free
Recoloring an image is more than swapping one color for another: it means changing the hue of an object or zone while preserving its texture, shadows and highlights. On a photo of a rose you want to turn blue, or a butterfly whose wing color you want to modify, simple color substitution is not enough. The tool needs to understand that the red of the flower includes dozens of different shades — from pale pink to deep red to the burgundy of the shadows — and that all of them must become the equivalent shades of the target blue. This is exactly what Flowfiles does with HSL mode and luminosity preservation.

Recolor an Image Online →Hue, saturation and lightness are the three components of the HSL model. Hue is the color itself (red, blue, green...). Saturation is its intensity (from neutral gray to pure vivid color). Lightness is its brightness (from black to white). On a red flower, every petal contains pixels whose lightness varies considerably — lit zones are bright, shadows are dark — but whose hue remains broadly in the reds.
When luminosity preservation is enabled, the tool replaces only the hue and saturation of each pixel, keeping its original lightness. Result: the lit areas of the red flower become light blue, the dark areas become dark blue. The flower keeps its volume, its petals retain their texture, the image stays natural. Without this option, the flower becomes uniformly blue, flat, photographically unconvincing.
Tolerance controls the width of the hue selection. A higher tolerance includes pixels whose hue drifts further from the color picked with the eyedropper. For a flower or butterfly with an extended color spectrum due to shadows and highlights, a tolerance of 45 to 65 in HSL mode generally gives the best results. For more uniform objects like a logo or digital flat fill, a tolerance of 15 to 30 in RGB mode is more precise.
Replacing a color targets a specific color and swaps it. Recoloring is broader: it means changing the hue of an object while preserving its shades, textures and luminosity variations. Flowfiles does both by maintaining the original light structure of the image.
Use HSL mode with luminosity preservation enabled. Click on the main clothing color, set tolerance between 40 and 60. Shadow zones from folds and lit areas on the fabric will be automatically preserved in the new color.
Yes, using the multi-rule system. Add one rule per color to modify — for example one for the red petals of a flower and another for its green leaves. Both rules apply in a single pass over the image.
Yes, via a graphical color picker or by entering a hex value directly. You can target an exact color (a Pantone converted to hex) or use the picker to visually choose the desired hue.
