I have some Schaller machines like that that are that snot-green. But most of that style are a much lihgter cream/light green colour.

I now use Klusons for that style which have much lighter coloured heads.

I get them from WD Music, who now own the Kluson brand name and make them.

They aren't that expensive for the basic tuners, these no Kluson name stamp ones are £33 for a set, though you'll also need adapter bushings for 10mm holes. https://www.wdmusic.co.uk/hardware-p...o-stamp-p13262
