I have had a go at producing a jersey express liveried f27 but unfortunately I am unable to get the fuselage to take the colours so it remains grey but the tail and wings I can see the new paint scheme what have I done wrong???

Sorted the problem with textures now seems I was editing the wrong texture  folder in paint and then saving it under the wrong file name. I have now done several repaints and theres no stopping. Thanks for your help...
