From my North American viewpoint, the first picture is quite colour coordinated. The yellow in the tie, hose, and garter ties, bring out the yellow stripe in the kilt tartan. in my eye it emphasizes that part of the Gordon tartan that distinguishes it from many similar tartans. I think the colours really look great together. Please note that the waiscoat has all of the kilt's colours in its pattern.
