I am working on a minecraft captcha code, as you can see in the video, it sometimes picks very similiar colors to background/a line. Which makes it very hard to solve. Is there a way I can avoid this? The captcha image is a BufferedImage and then displayed to a minecraft map so I won't put minecraft tags on this thread.
