We are currently looking for a suitable clinker for a townhouse.
Directly before your question, wrote - whose house can be seen here with very little scrolling back. Is his gray too light and/or not speckled enough for you?
We recently had the clinker color question here as well - quite regularly - discussed: - especially #22 you should read on that.
Or you can take a look, for example, at or or .
Besides much that others and I have already said there, I specifically want to point out regarding the topic of "lively color gradations": such things absolutely require an "old hand" for processing, you have to have a knack for it. If done by trainees - possibly even in poor lighting - disgraceful results will be produced.
