Accurate color measurements by (optionally) using a white reference to compensate for varying lighting conditions, thereby enhancing precision.

Are you missing any color space? Let me know at apps@contechity.com and I will try to add it.
You can see all the color spaces at once, click on the ones you are most interested in for a graphical representation, hide them, or reorder them.

The Power of the White Reference
What sets Color Meter apart from other apps is its innovative use of a white paper reference. By compensating (automatic calibration) for the color and intensity of the ambient light, Color Meter ensures that the color measurements are more precise and reliable. It is like having a professional meter in your pocket.

Perfect for artists, designers, architects, decorators, researchers, print technicians, photographers and anyone interested in colors.

Use the app as for color calibration, experiments, color identification, palette creation, color analysis and more - the possibilities are endless.

Perfection, and exactly what I needed! This tool allows you to measure the exact color, in multiple formats (RGB values, HEX, etc). While it is not required, I found the option of a white reference to be ideal! This means that you can add a white piece of paper, or similar, into the frame, and identify it as white. That way, the program can determine if there are any color biases in the light, and can effectively "subtract" that bias color in the light from the color you are measuring.

Exceptionally useful for me as an artist. I've already had a surprise at how subtle the differences in luminosity and hue are between flower petals in the sun and shaded petals. It is also very useful for finding the base color of a subject that is in a color that my phone's camera just can't handle correctly, like bright reds that tend burn out or go orange in cam photos. I really would like to see a user forum on your website so that users can share hints and tips.

Works exactly as one would expect. Very useful for comparing color swatches objectively and testing lighting changes.
