HA..Well, I don`t know what a/the HEX value is, so I can`t help you there, I can tell you that the color I put on the right wing in s.tga file is real close to blackest gimp can achieve, my goal was to knock down the glare on the white almost as much as possible. if you can tell me where to locate that value in gimp, I might be able to help with that. After all these years I still don`t deal with layers Alpha layer...what the heck is that, I sort of have an idea Buuuuut, still not exactly sure...RGB layer...Well to me, (and correct me if I`m wrong) that`s the .tga file, well, at least to me, SO, back to point, in/on the .tga file, all I did was color the panel lines a light to med. gray, and the rivets a fairly dark gray, they didn`t stand out as much with the med. gray I used on the lines, so I went with a darker gray. Looking at the two pics. above, it appears the right wing lines are darker than the left wings, So, did you only do one wing darker for comparison, or are they both the same, or, is it`s just the pic. giving that impression..??...ANYWAY, I would say looking at the right wing, yours looks just slightly darker than what I got, but still looks good....... TO ME, the whole point is to make them visible to the point that they can be seen, but not so much so that they`re unrealistic (to dark) after all they`re just shadows in the real world when you think about it
