Determine RGB, HSV, and Hex values for any color. Use the Color Mixer to find the perfect color by using the sliders to adjust just the right amount of red, green, or blue. A Grayscale Meter makes determining the right mix of RGB values to get the gray you want. Select a photo from your photo library and tap on any part of the photo to get the RGB, HSV, and Hex values of that spot. You can zoom and pan through your photo using your fingers. If your device has a camera, RGBer lets you snap a photo, zoom and pan to the area that you want, and tap on the photo to get the RGB, HSV, and Hex values. Afterwards, you can save your new photo to your camera roll for later reference.
