LumaMatch is a powerful desktop application for scientists, designers, developers, and artists who need to find two different colors that share the exact same luminance (perceived brightness). Using advanced optimization algorithms, LumaMatch systematically searches and fine-tunes color variations to find perfect matches, even for challenging color combinations.
This tool is ideal for tasks where visual contrast and harmony are crucial, such as creating accessible designs, ensuring readability in user interfaces, or achieving specific artistic effects in digital art and photography.
Web & UI/UX Designers: Ensure text and graphical elements meet accessibility standards (e.g., WCAG) by checking luminance contrast. Create sophisticated and balanced color palettes.
Graphic Designers: Develop visually harmonious designs where different colors carry similar perceptual weight.
Digital Artists & Illustrators: Achieve unique artistic effects by using colors that are distinct in hue but identical in brightness.
Photographers & Videographers: Understand and manipulate color luminance in post-production for balanced compositions.
Developers: Build applications with a strong focus on color contrast and visual accessibility.
Scientists (e.g., Cognitive Neuroscientists, Psychologists): Precisely control the luminance of visual stimuli in experiments. Ensure that observed effects are due to color differences (hue/saturation) rather than unintended brightness variations.
Advanced Luminance Matching: LumaMatch utilizes a sophisticated multi-phase search algorithm to find pairs of colors with nearly identical luminance values.
Perceptually Accurate Calculations: The application uses the ITU-R BT.709 standard with gamma correction for highly accurate luminance calculations that reflect true human perception of brightness.
Systematic Color Exploration: By generating thousands of variations in the HSV color space and employing gradient descent optimization, LumaMatch can uncover matches that are difficult to find manually.
Grayscale Comparison: Instantly see the matched colors converted to grayscale to visually confirm that their luminance is identical.
User-Friendly Interface: Simply input two color names, and let the app do the hard work. The results are displayed clearly, showing the original and optimized colors.
LumaMatch is available for Linux, macOS, and Windows. To install the application, please follow the simple steps below:
Download the Application: You will find a dist (distribution) folder in the application's main directory. This folder contains the installers for each operating system.
Run the Installer:
On Windows:
Navigate to the dist folder.
Double-click the LumaMatch-Setup-X.X.X.exe file (the X.X.X will be the version number).
Follow the on-screen instructions in the installation wizard.
On macOS:
Go to the dist folder.
Double-click the LumaMatch-X.X.X.dmg file.
A new window will open. Drag the LumaMatch application icon into your Applications folder.
You can now launch LumaMatch from your Applications folder.
On Linux:
Open the dist folder.
You will find an AppImage file, for example, LumaMatch-X.X.X.AppImage.
Make the file executable. You can do this by right-clicking the file, going to Properties, then Permissions, and checking the box that says Allow executing file as program.
Double-click the AppImage file to run the application.
For scientific applications requiring precise luminance control, while LumaMatch provides highly accurate calculations, it's crucial to perform a final verification on your specific experimental display. Due to variations in monitor calibration, always visually inspect the grayscale equivalents of your LumaMatch-generated colors on the target screen to ensure they appear identically bright. For the highest precision, consider using a photometer to objectively measure and confirm the luminance output directly from your display.
