HueShifter

HueShifter is an amazing new application for doing color transposition or "color shifting" within images. Unlike other graphics applications, HueShifter works in perceptually uniform colorspaces (Lab and Luv) while letting you select and manipulate colors using dimensions that you're familiar with - hue, saturation and lightness. This allows you to make changes that are imperceptible and that look completely natural, changes that don't have halos and fringe effects around the affected colors. Open, drag or paste images into HueShifter, then save, drag or copy the results to another app. You can save/drag/copy either the color image data or the selection mask to use as a layer mask in another app. Plus HueShifter supports images with alpha and maintains embedded color profiles. HueShifter works in real-time as you drag its sliders. It's multi-threaded so it makes use of that fancy multi-core processor you have, plus it's efficient and doesn't waste your laptop's battery or your time watching progress bars. With HueShifter, you can... Transpose colors • Change product colors without needing to re-photograph the product • Make numerous product shots by only shooting one color and using HueShifter to produce the other versions • Re-color logos or artwork • Re-color web or ui elements to make them uniform and the exact same hue • And do it without degrading the image like HSL/HSB/HSV modes can Saturate, desaturate, lighten and darken colors • Neutralize slight color casts in white or gray backgrounds • Highlight subjects of interest by desaturating other colors Purify colors • Pull a range of colors to a new single color • Shift or remove color casts in shadows, such as purple casts in shadows on blue objects HueShifter was designed to work alongside Photoshop and other image editing applications… • Use copy and paste to exchange images with other programs • Make selection masks for use back in Photoshop or other applications • Supports color-profiled images, retaining the original color profile when copying or saving images HueShifter is perfect for users who don't own Photoshop... • Make color changes and corrections without having to own an application like Photoshop • Results are achieved faster and better than with other apps • Visual results are more uniform than is possible with other apps
