How many colours are there is a rainbow? I would like all of them in my wedding please.

The colour scheme just kept changing. First my boyfriend and I agreed on tiffany blue, white and yellow (not necessarily together), cos we wanted fun and vibrant colours. Then my mum said blue is not a nice colour when seen in real life. So she suggested maroon, which we later decide on maroon and gold. Then... my dad.... he's been so loyar burok this past few days, he commented all these cost are unnecessary expenditure and expensive. So I asked what he meant... he said.... "no need pelamin lah". Wtf. *facepalm*

My boyfriend and I did not expect picking a colour to be this difficult.
