The house exterior in lemon yellow or sun yellow? A bedroom in strawberry red? RAL iCOLOURS shows how things could look. With this app for iPhone and iPad, you can now recolour the objects in your photos with any RAL colour – quickly and easily.
In only three steps, anything can be recoloured with RAL iCOLOURS:

1.Take a photo with your iPhone.
2.Select one of 2,328 RAL colours.
3.Recolour the object in the photo.

RAL iCOLOURS is as useful as it is inspiring. Painters, architects, graphic designers and Web designers can now make it easier for their customers to make colour decisions. With the RAL Colours app, you can quickly give them a picture of your colour concept. You can present colour designs to your customers on site and display alternatives directly. And you can save your colour selection by project name and send photos of recoloured objects via email.

The app’s colour palette includes the RAL CLASSIC and RAL EFFECT colour collections and all of the colours in the RAL DESIGN System – all 2,328 RAL colours. The corresponding L*a*b*, sRGB, CMYK and LRV values are listed for each colour. And RAL iCOLOURS is also compatible with COLORCATCH NANO, the Colorix colorimeter. This device incorporates a revolutionary new technology to accurately measure the color of smooth, structured or patterned surfaces to determine the corresponding color of the preselected swatch. NANO reads and measures 50'000 pixels separately. During reading it eliminates automatically all non-dominant colors such as shade effects and dirty surfaces.

For better understanding of the functions and use of the App, please watch the demo on the video first.

Great if you are looking for RAL LRVs

I bought this app as I was looking for light reflectance values (LRVs) for contrast calculations. Perhaps a niche use but valuable all the same

Very poor colour likeness to RAL colours

I would not recommend this to anyone who is looking for any measure of accuracy in the colour reproduction. On my iPhone4s the colours are very different from the regular RAL colour charts, and it's terrible when compared to RAL Design colours! I have contacted Colorix and they say the iPhone cannot be calibrated to solve this problem, so the App is pretty much useless and I will be deleting it. What a waste of £6.99.

Good app

I'm a designer and this looks good and works good. Would be better if there was a tutorial within the app. And in future ?? a real time colour changer for surfaces though the camera as you move around.
