ColorKit: A Color Assessment Utility App

For this week’s #idevblogaday post, I’ve written a small utility app that’s freely available for download on github.

ColorKit is a tiny iOS app (iPhone) which allows for quick and easy color-sampling for a UINavigationBar + UIToolBar. It allows developer to easily assess the appearance of tintColor on the device.

Last week, I talked about adding textures and depth in your app, in particular to a UINavigationBar. While this effect is great when used appropriately, UINavigationBar’s tintColor property is extremely handy and useful to give your app a unique look with one line of code.

Finding the right colour for your app can be a bit of a hassle, especially due to differences in colour appearance depending on which monitor or device you’re using. Furthermore, UINavigationBar and UIToolbar are coloured with a gradient and has a glossy shine, so knowing exactly which RGB value to use is often impossible.

ColorKit builds and runs right on your iPhone and makes it extremely easy to quickly play around with various RGB settings to find the perfect colour for your app.

Inside the app is a UIImageView which allows you to add a screenshot from your app to better see how the colours may look with your UI.

You can download a copy of the code here:

Pro-tip: Do not use bright colours. Play around with the values to create more “faded” colour. Brighter colour wash out the title text and generally look horrible.
