thank you x4btr

Your right about the A24m Green I used. The I-153 was metal, wood and fabric construction and I didn't think they would use two completely different paints for just the metal parts then switch to another type just to paint the fabric covered portions. Doing that would have shown up in the color photographs I have seen and they look pretty uniform in color and hue to me.
Based on that, I guess it's because I liked how A24m was on the skins I made.
It's nice to discuss these matters and get different opinions and with this template, I would hope others more versed on the I-153 would make some really stunning skins for all to enjoy.
Thanks for your explanation!
