Ooh difficult one. I think a very practical tip might be that when you are thinking of a colour scheme, maybe have a couple of colours, so for example if you do pick a certain shade of pink, maybe accent it with a silver, gold or pearl (or anything) so then when you are choosing other parts for your big day, if you can't match the pink of your bridesmaids perfectly, you have your second co-ordinating colour to work with. With your invitations we can usually match any colour but the amount of couples I've spoken to who've struggled to match the dresses to the ties, or the shoes to the chairs is a lot and when you are planning a wedding you want to save yourself stress wherever possible.
