Hi Shado,
The 3 finishes were specifically chosen due to trends in furniture designs and the most popular colours offered and sold within that industry.
Off course, it would be great to be able to offer a wider range of colour options but as a manufacturer you have to be careful not to fill your warehouse full of colurs that don't sell.
We also have to look at historical data and which finishes were more popular than others, this forms part of the decision to make the colours we do. Trust me, if demand was there, I'm sure we would do something about it.
Reference Custom Colours is something completely different, these are premium products which sell in much less quantities than our Q Series, plus, they are made here in Maidstone, so it's easy for us to react to a specific demand, albeit, at a premium on the price.
All the best
Ron
