They were delivered in lined green with whiskers, red bufferbeam, white tyres and a grey roof.

In 1962 yellow panels began to replace the whiskers to provide better visibilty of oncoming trains.

Some did appear in this early blue livery variation in 1967. The BR arrows would be on the cab door, and the vehicle numbers would be 3" high. They would have red bufferbeams, but not the white cab roof domes that some classes would.
As with many classes, mixed livery sets in the changeover era were not uncommon, one vehicle in blue and one still in green. This image on flickr shows two sets, each with one vehicle still in green and the other in blue with a small yellow panel.
Another livery changeover period experiment was a full yellow end with the cab doors also painted yellow which was applied to at least one Class 113 vehicle — see the rear vehicle in the image below. See also the rear vehicle on the image on page 12 of the book "Heyday of the DMUs".
In 1967 all blue livery with full yellow ends became the norm. This was not long before all the 112/3 vehicles were withdrawn, and there was still tremendous variety in the location of the BR arrows and location of the numbers. In this image on flickr, with three vehicles in view, two have the BR arrows on the cab door, one has it under the front passenger sidelight. The vehicles numbers are 3" high (4" would become standard) and the vertical location on the bodyside varies on both the vehicles they can be seen on.
