About this app

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

The app measures colors in real time by using the camera of the device and can be used as a live color picker (color grab) or color detector. Also known as a colorimeter.

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.

Nice app, big help trying to match colors without a dedicated meter. It would be nice if the sample window was a bit larger or had some zoom, it's not always easy to see if you have it pointed at the correct spot. Lots of options for different color spaces

Thank you so much for your great review! Yes, I plan to make the sample window adjustable in size. Hopefully I soon will find the time to implement that! Thanks again!

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.

Compared Color Meter results from several phones against a just calibrated X-Rite spectrophotometer and none were close enough that I'd consider them useful. Checked against several Pantone targets in various lighting conditions (including outdoors) and the individual results and averages were always useless. Might be good enough if someone was painting an entire house or room, but not for anything requiring app's supposed "Accurate color measurements." Update: gave app a second with same result

Thanks for your feedback! Obviously you will get better accuracy with a standalone professional meter that costs 200 times as much as this app does. Thanks for stating that this app could be useful for someone painting a house or a room. What is your use case? Thanks again! apps@contechity.com
