Why am I not able to get accurate colors on my Kanvas 27Pro 60hz?

Hello! I’ve owned my Kanvas 27Pro since October of last year. I really do love it but no matter what I do, how long I fiddle with the settings and adjust the colors, it’s never accurate. I have contacted huion about this in the past and it lead to nothing. Is there anything I can do to help? I’m aware there is color calibration devices but from the looks of it, an accurate one will cost around $200 which I don’t have the money for at the moment. Is there a program I can use? I used windows 11.
