My outdoor equipment always has some type of high visibility marking on it whether it is the items coloration, an added reflective strip with day glo trim (which I prefer) or a glow strip.

From there the item can go into a pouch or pocket, which is a little more subdued. My packs and pouches are either camo or black, but the pack has the previously mentioned reflective strips with day glo trim on easily removed velcro straps. I do this just in case I don't want to be so visible.

I also carry orange marking tape in case I need to up my visibility... Or mark a trail...
