Carpet spray dye

[Griffer]

Last year sometime remember seeing on here about suede dye in spray form used to succesfully re-colour faded carpet patches. My black wilton is faded on the doors and rear shelf but is all in good condition so want to give this a try but have been unable to find anywhere that sells suede spray dye, can only get it in touch up bottles like shoe cleaner, any ideas where to buy anyone? Thanks in advance.

Timpsons sell the shoe dye. You can water it down a bit for carpet dying.
