I have a question in psett 4's, "whodunit". Is it even possible to isolate the colors in order to bring to the foreground "whodunit" ? Because when I elimanate the red I can see a 'light bluish' person in the image holding something but when I try to whiten the other colors (in order to bring forth the colors) it turns the image completely WHITE?! However when I look closely at the bmp, I see 'light blueish' colors pretty much everywhere; with that being said, how can we bring forth "whodunit", when all the other "RGB" values consists of the same combination colors of "whodunit"? Do see what I'm saying??

  • You asked the same question 3 days ago and I told you to use xxd to see which colors are in the image.

Chris is correct, you should look at the hex codes to see all (or most) of the colors. I have a sneaking suspicion you've removed ALL the red, and you don't want to do that, further up in the (hex representation of the) image you will see the varying hex codes that are actually part of the image that require red.
