Totally agreed. Having whole windows elements in one color is a bad idea. Like we have monochrome displays.
1. Ammo and item colors should differ (there are already examples).
2. Table heading should have more neutral color.
... Textual content have to be colored anyways, and not only for this window! Probably columns better to be having different colors,
N. Quantity/Sall/Sack columns as other numeric fields should get right alignment, and "^v" buttons visually have to be between them (for the moment they are closer to left column)
