Blue Suede Shoes

Any tips on looking after Blue Suede Shoes?

I use Saphir Medaille D'Or Tinted Renovator Suede Spray 250ml for black ones as they have a tint, but can't seem to find a blue equivalent.

I'd just use a standard non-tinted suede protector for them, and use a suede brush regularly.

for whatever reason, one part (a side panel part) has faded, where as the rest is fine. Not sure how to get it back to normal?
