Dear author, may I ask you a question? 微信图片_20210724130313

I have a question about the yellow sentence，When the absolute values of RGB are （0，0，0）, shouldn't the resultant flow field be black? Why did the paper say it was white. This question has been bothering me for a long time. I am looking forward to your reply. Thank you！

You can map x to 255 - kx so it will become white.
