The collection comes complete with a Neutral Strip of 11 black – white colours, a palette to be used for colour selection, testing sleeves plus a pair of gloves to avoid soiling of the poms. However the acrylic shelf featured on the image has been discontinued due to extensive damage during transit This Traditional Atlas is ideal if colours are to be used in one location such as a design studio and it is packaged into a strong outer case.

The Portable Atlas has the same 1080 colours packaged into 6 trays with each tray holding 4 Chromatone triangles of 45 poms. This enables the full spectrum of colour to be viewed at a glance and allows instant colour selection.
