Hi Sandy,
Angie is in the Netherlands this week, so she won't be around as much as usual. Perhaps bump up this thread again next Monday?
In the meantime: I think you can use as many colours as you like, but perhaps to not feel overwhelmed try coming up with a few mini capsules within your larger seasonal capsule and use Angie's advice for this (pulled from this blog post):
The first thing you need to do is choose a colour palette to simplify the mixing and matching. Neutrals are especially simple to remix, but adding the right amount of colour can look just as professional.
The possibilities are endless when it comes to the specific colour
palette you choose, but generally you need some conservative neutrals as
the base, and colourful hues to make things interesting.
For example, black, grey and white, with splashes of teal and
amethyst. Or brown, camel and cream as the base, with chartreuse and
antique blue as the pops of colour.
So each mini capsule would then have one to three neutrals and two other colours (use your favourites for this).
