Melmothtw, is quite right. We trialled several colour schemes in 91 on the Wessex. All over Matt Black made them stand out as a dark shadow at night, the low viz Grey did indeed make them glow and the best result came from the new two tone green which was adopted by both Wessex and Puma. A vast improvement over the older Grey Green Scheme. This was held up by several Fast Jet Pilots who were working up for Bosnia at the time using 60 Sqn's Wessex as targets and the new scheme made it very difficult for them to acquire visually.
