IF tan says blue after meeting...?

If he turns us back blue after the meeting how long can it be till we play in blue at home.. is there any way of switching our home and away kits for the rest of the season???
This would give us a massive boost if true and would really drive on our promotion bid

I'd think next season, but if Chelsea/Liverpool can advertse new kits during the current season and play with them, why can't we?
