One advice if you want to better the colour, is to carefully apply the wanted colour with shoecream. Rub it in extremely gentle and polish it hard after awhile...as you do with shoes! Spraycolour for shoes may also be an alternative.
I have a Concor suede saddle ca. 1979 that's more like nubuck now. I've used Sno-seal on it, sparingly. Whatever you use, don't use a lot, and don't use anything that could stretch the leather, eg. oil-based products.
