Despite a reasonably strong launch of Color Splash Studio, MacPhun took some very bold actions to revamp the app’s image, including a name change to ColorStrokes. It’s nice to see developers put a lot of effort and passion into their creations, although, we’re happy things have calmed down again. As a much more typical update, ColorStrokes v2.1 contains optimization for the latest iDevices, mobile OS, and more.

For iPhone 5 and fifth generation iPod touch owners, having an app finally take advantage of the larger Retina display, and remove those annoying black spacer bars, is an obvious gratification. However, all users shall be pleased to hear that performance, especially image processing, has been increased by up to two times, plus there are more shades of color to choose from when using features such as ReColor.

As a bonus, MacPhun has teamed up with AppAdvice in order to offer you a chance to win one of five promo codes for ColorStrokes ($0.99) for iPhone and iPod touch.
