I'm worried I won't like my season
I would encourage you to explore your own colouring, so that you understand what suits you best. You would naturally be drawn to the colours in your own palette, in which you look your best, where your face, rather than the clothes you are wearing, is the focus of people's attention. Its all good.
As an adult, of course, nothing would force you to 'accept' such colours. Even if you keep strictly to your colours as soon as you find put about them, it would usually take some time til you have replaced everything in your wardrobe. Once you do, though, it means that everything 'goes' with everything else. It makes packing easier, and less scramble to get shoes to go with a new outfit, as most likely you already have something that would work.
Its the reason that so many people find black 'easy', because its easy to find things in black and seems easy to get things to work together. The pleasure that comes from finding your own things, in your own colour and style, is immense. I find myself feeling better when surrounded by my own colours,
Over time, though, you will very likely notice the impact ’your' colours have and find yourself choosing them. If you ever spot anything that is perfect for your colouring and style,you can be confident buying it, no matter what the cost. Many people find that the confidence that comes from knowing your colours, also means that you can afford to buy fewer, and better quality clothes.
Hope you find it for yourself.
If the cost of being analysed puts you off, you could look out for the colour me beautiful training academy, who occasionally run training courses for new consultants. The academy offers free sessions to people prepared to be models for the new consultants. They are closely supervised, and their judgement is validated by the supervisor, so you are unlikely to be done incorrectly.
You could work it out for yourself, but its good to have someone validate it for you and point out the colours within that palette that particularly suit you.
