I used a firm called Diginate.com online (
https://diginate.com/) it cost £17.60 for 3 stickers incl postage and I designed it online using their design tool ( I'm not experienced so it must have been easy!) I just used the standard red which looked very close, I did research the Ineos colours (
https://www.ineos.com/globalassets/...oad-2020/30582_ineos_brand_guidelines_v14.pdf) off their brand site and it appeared to be RGB 213/43/30 whatever than means - but it looked very close to the standard red at Diginate!
If you go to Diginate the design was saved as Grenadier and the order number was D84827 the decal comes pre cut and it fits. You have my blessing to see if you can get a repeat of the design
Hope that helps
