I was pleased to get a comment from Mikkel on the subdued colours I had used on the engine shed. Despite not achieving his amazing standards I thought I would share how I do it. Subdued colours are something I am aiming for on the layout as I always like the layouts with subdued colours at shows. On the engine shed I used The Gimp to subdue the colour of the printed Scalescenes Red Brick, however on the other areas and all over the rest of the layout I use pastels. I have two sets that I rely on:
The Black to White set is from a high street branch of The Works having seen a recommendation from BRM's Phil Parker. I picked up the landscape set at a show such a long time ago that I do not remember who sold it to me. It used to be available from Amazon but I have not been able to find it there recently. I did find one on eBay. Fortunately I have a spare!
On all painted surfaces and the scenery I paint using standard colours and then dull down using similar coloured pastels. I often use a few and then blend them on the surface with a dry brush. I like the finish not just for the colours but also the soft edges and the very matt finish. It works particularly well on ground cover and stone surfaces. They clean up well using the vacuum cleaner extension and can be sealed using a spray varnish if necessary.
The signal box was finished this way after being painted with Precision Paints GWR light and dark stone, plus Humbrol brick red and slate colours.
