Harness Leather Heat Damage

[wyomingcowboy]

I made some saddle bags out of some 9/11 oz Hermann Oak russet harness leather that turned out pretty well. I had them in the pickup this July in high 90's temps (out of direct sunlight). When I took them out to show them off they distressed a little where the leather "flexed" or what have you. The color changed and has not returned. I recently oiled them with straight neatsfoot all over. I did this twice and didn't spare much oil. The leather soaked it all up nice but the original colors (heat damaged and all) have returned to be exactly what it was before the oil. I have tried buffing with some artificial sheepskin but the color doesn't appear to be changing at all. Have you any ideas as to what I can do?

I like the bags but can't really afford to keep them for myself and I don't want to sell them as is.

Ideas?

TIA
