Polish pikolinos olmo shoes that are faded type polish or dye service that does this

Essentially what you did was just dubbing them or waxing them. Shoe polish is wax based product and one could think of it as a colored mirror on shoes, I've applied burgundy, black, tan and dark brown polishes on my brown shoes, yet they don't look burgundy or black but it's a nice variance of all.
But the main point is that the I fear that the polish will wear off in time and reveals the unpolished suede. Why didn't you just recolor them? I'm very sure there are some products meant for recoloring suede.
And before the waxing you had already a pair of winter beaters, suede is more strong than you think. Yes you can walk in the rain with suede without it exploding. All you have to do is to protect them with nano sprays and call it a day. And I always like to post this when talking about suede.

You can get a shoe dye to take care of this yourself at a shoe repair shop. Fiebings and Meltonian make good dyes and others make some too.
