PennineRadar
Regarding NODE - I was able to find a high quality BMP of the radar display in a PDF I once found and pulled the colours from it, these were the numbers I got
Background -> 0
Any Airspace lines -> 7a7a01
Green Radar Tag Labels -> 45dd67
History dots -> 84bc
Map 6 4e6f00
Map 9 4e6f00
(on the BMP range rings had a slight green tinge to them, which I believe the majority of the sectors use, although I have noticed GW INT/FIN have dark orange)
TitleBar1 7777a8
TitleBar2 7777a8
TitleText ffffff (should be white on my screenshot)
EDIT (forgot to add):
Selected level -> 02a3e8
(Screenshot might not be colour profile accurate)
Also having to use override High DPI on application to get a crisp picture, but makes menus look funny!
