Hello, The problem with colour recogniser apps is not the camera. The problem is the inconsistent lighting. For sighted people, colours look different based on how much light there is. This is a concept which is very difficult for blind people to comprehend. The way specialised colour identifiers work is by housing the light next to the lens of the camera. One places the identifier directly on the colour item. Because the device is tuned to the specific light used in the device, a person always receives a constant result.
In the real world, the darker the ambient light, the darker the colour - and this is the case across the board, for all colours. The only way to constantly get perfect results is to go with one of the expensive, specially built colour identifiers. It is impossible with devices like the iPhone. The light is not mounted around the lens. The light is close to the lens, so if you place the iPhone against the item, you block all the light and the colour becomes black. Sorry folks, but this is the way it is, and whining about it will not change the laws of physics - ever!
