Need to repaint accessory brackets, need opinions

I'm gonna start cleaning a few things up in my 'bay again, and my first task is to redo my accessory brackets. I want them painted a color that will make them disappear...i don't want them to stand out and look stupid. I don't know if black will really do the trick either because i don't want big gloss black parts right in the front of my bay, and i don't think flat black will look right. I don't want them to stand out and pop out and be the first thing you see. What kind of color might work for this? I also wanna keep it as factory looking as possible (nothing like having '03 Cobra power in a factory looking engine..lol).

Here's a shot of the engine bay for reference:

I'm also debating on having the breather lid, intake and valve covers all poweder coated a bare aluminum color, to get them back to as stock in color as i can. The original Powered By Ford covers were raw aluminum like the intake and the lid was machined. The breather base was a satin black which i may repaint to get back to that color instead of the flat black.
