NOJ and Jakopovic comparison

Here you can see a comparison of three sets:

NOJ 1950 made in 2014,  "Jakopovic" 1950 and "Jakopovic" with cross.

I don't know exactly when this "Jakopovic" sets were made, but probably in the 50s, early 60s.

All three sets are made of maple and walnut. NOJ and "Jakopovic" with cross are weighted. 

The first piece is NOJ, the second "Jakopovic" 1950, and the third "Jakopovic" with cross:

No, it depends on the wood and maybe the finish. Walnut is very colorful. I think that's why they didn't use it much for the mass production of chess pieces. It can be reddish, greenish or brownish and in lighter and darker variants. These rooks are all walnut, personally I don't think there are two of the same color?

This happens if the walnut is not carefully selected for a set of pieces. The knight and pawn are very light, the bishop and rook are dark, and the king and queen are something in between:

In addition to Suboseg's points, the differences in colours might also be influenced by the type of coating applied such as varnish, beeswax, lacquer, or similar finishes. These materials affect how light reflects off the surface, which changes the way we perceive their colour (and consequently the colour of the wood underneath).

Over time, these coatings also age differently. For example, it is noticeable that the pieces from NOJ have developed a beautiful golden patina over the last decade, which I personally find stunning.

@felonet the colour of the walnut pieces remain pretty stable. What’s changing, very slowly, is the colour of the pieces in maple which are developing that characteristic golden patina.
