Hope the colour info is of help:

Regarding a leather spray to lighten your seat colours.
The only option will be to contact a leather renovation company that deals with classic cars and ask to buy some of the correct colour dye.
Look in the back of the 'Classic cars' magazine.
Several companies listed such as:
www.furnitureclinic.co.ukThey specialise in re-colouring car interiors and sell d.i.y kits.
Be prepared for 'OUCH' though... They quote £50 for a kit.
I bought a VERY tiny touch up bottle of light cream for my own real Jag from Ebay - £30.
The bottle is the size of girls nail varnish bottles.
Other than that, use ordinary acrylic car paints.
You'll be surprised at how flexible they are but getting a match might prove difficult.
