Any chance of fixing this?

Hi everyone, hope you are all enjoying the weekend.

I would appreciate everyones suggestions & advice

Yesterday, I was painting my car and upon mixing second coat i accidentally put my finger that had a few drops ammount of paint into a can of 2k paint thinners to pull the lid out as it was stuck (silly, i know). This left traces of dilutted paint and thinner around the lid inside the can so when i poured some out, it was slightly mixed with the paint colour.

Now my question is, is there any way to fix this?
Or would i have to throw the whole 5L away unless i use to paint same shade / colour?

If there is no way to fix this, would the next paint jobs i do using the same thinner be a different shade as this thinner is 90% clear compared to brand new?

Thank you.
