## What is RAL iColours?

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.

Figured I would try this App as it listed 2000+ colours compared with the 200 in the Classic colour books.
