ColorAssist 4+

Use the camera to capture RGB values in real-time and convert them to the closest color name from a dictionary of nearly 900 colors. Also available: RYB, HSL and CMYK values, HTML color code, closest HTML color name, and simple color name.

Touch a color square to view the information for that sample at any time.

"Auto" uses the camera's auto focus and auto contrast adjustment feature. "Lock" fixes or locks the current contrast setting. And "Target" allows you to touch any area of the screen to select that spot as the source for the color sample (in cases where moving the device would disrupt the focus/contrast, or where the device is mounted in a fixed position).

Manage named color sample sets on the Edit screen. After organizing a sample set, email the color samples with color chips, with color chips and a selected photo, or as text only.

On the Options screen, select which color conversions to display, and set the spacial and temporal apertures from 1x1 to 50x50 pixels, and 1 to 30 frames.

Touch the "Target" selector then touch the screen to move the sample location without moving the device.
