Adobe recently released a new iPhone app called Kuler that let's you extract colors from your surroundings using the phone's camera. It's a useful tool that allows designers to capture color inspiration wherever they find it and easily incorporate it into their work via color palettes.
The app also highlights a weakness in current display technology: no display on the market today can actually reproduce all the colors we see in the environment around us. So, even if the camera sensor can capture that color you love, you may not be seeing an accurate representation of it on your device.
The iPhone 5's LCD display is designed to cover the sRGB/rec.709 color gamut standard used for HDTV broadcasts. And, it looks great but compared to the world we see around us, it's just not quite as rich. If we plot the iPhone 5's color gamut against the gamut of colors found in nature, the phone comes up short in important reds, greens and cyans:
If DisplayWeek 2013 was any indication, color has once again become a hot topic in the display industry. Color gamuts are getting larger and it may not be long before we see a display that can match what our eye sees in nature. Over the course of the next year, we will start to see more wide color gamut-capable devices as OLED continues to expand marketshare and new technologies like quantum dot LCD begin to enter the market in volume.
