ColorChange

See a demo of ColorChange on YouTube! Search for "ColorChange iPhone app".

ColorChange allows you to take any image and manipulate the colors to allow you to easily visualize what a room, landscape, person, or object would look like as a different color. With its unique "Magic" selection tool, it makes it easy to select desired areas of your image, and lets you change the colors with ease and flexibility. When colors are changed, you can choose the degree of the original image to maintain. This allows you to do things like make a persons skin green, the sky yellow, wash an entire image with color highlights, or paint your walls black!

ColorChange is perfect for interior designers, decorators, or do-it-yourselfers looking to choose that perfect paint color. It is the first tool designed specifically for the iPhone that gives you timely visualization of your next painting or decorating project - never pick a bad color again! It is also great for people that want a versatile toolbox to do color editing of images on their iPhone. With the simple but rich set of tools provided, virtually any image effect is possible. From washing entire images in color tones to highlighting or de-saturating areas of an image, anything is possible!

The "Magic" selection tool uses a combination of edge detection and adaptive smoothing to help you select areas of your image to manipulate. By default it is designed to work with the normal lighting of indoor iPhone photos, and can be adjusted for particularly dark or bright images. In addition to the "Magic" selection tool, you can select areas of your image by defining a polygon, tracing a region, or painting. You can then selectively remove areas of the selection with the eraser tool.

Choosing the target color is performed with a set of Hue, Saturation, and Brightness slider controls that let you choose any color of the rainbow. As you adjust the sliders, the selections in the image will automatically update to show the color changing in real time. A full screen color swatch can be opened to provide more information on the chosen color for automatic or manual paint matching. An additional Blend slider allows you to specify the intensity of the chosen color against the image - with it, you can quickly preview the original unaltered image (when the slider is at the far left) and gradually blend in your chosen color up to an overly intensified version (when the slider is at the far right).
