One of the things that can make colorization very time-consuming and tedious in other image editing programs is the actual choosing of the colors. With its vast Color Library, Coloriage offers a distinct advantage over many other applications. While you still have the option of defining custom color shades, the Color Library includes a number of palettes that allow you to quickly and easily choose a color for common items such as eyes, skin tones, wood, water, stones, and metals.

The diameter of the tools used to apply and remove the color strokes can also be easily modified by clicking on the tool and adjusting a slider. However, this method of adjustment can be a little unwieldy when you’re trying to pick an exact setting, and it would be nice if there were also the option to type in the precise value here.
Coloriage does an excellent job of both blending colors and recognizing edges, allowing you to change the colors of overlapping objects so that each one is distinct without any bleed over from surrounding items. Although that may sound simple enough in practice, it’s actually a lot harder than many realize and it can take a long time to manually achieve such results when constrained to working with standard photo editing tools.
In the end, I found Coloriage extremely impressive for the quality of the results that can be achieved with the minimal input of effort and time.
