Re: Appending two TIFs modifies hex values?

I see what you mean re: the same colors from the console. I am seeing the same (and thank you for the syntax recommendation). I have to pull these images into Gimp afterwards to reindex the colormap afterwards (long story), and that was where I was seeing the colors come in differently after append....

Here are the two commands...

Re: Using HSL and LCHuv to adjust hue on white image

@fmw42 - Strange that you were getting a black tie. I reran and still have the same result. The redish tie with the command netted me a dark purple tie. That aside, your other solution works quite well. It does seem that the result loses just a very small bit of brightness or luminance or white (I a...

Re: Using HSL and LCHuv to adjust hue on white image

It certainly makes sense to me to start from the white (https://s3.amazonaws.com/mtcarlso_help/help/white.png) and apply the values from there, I had just had success starting from input.png and so was working from there.

Re: Using HSL and LCHuv to adjust hue on white image

Ahh, I am sorry, I wasn't catching you fully. I will try that now. Thank you for the deep links. I am running the script through a few different colors, but here are 3 that I have been testing with: convert input.png -mask mask.png -modulate 22,200,30 royal.png convert input.png -mask mask.png -modu...

Re: Using HSL and LCHuv to adjust hue on white image

Using HSL and LCHuv to adjust hue on white image

I am trying to color the white (with black stitching) tie on this image [ https://s3.amazonaws.com/mtcarlso_help/help/white.png ] with some predetermined colors so that the stitching and light/shading details remain. I have met with some success but can't get quite close enough to the desired effect...
