Hello resolution!

It is tricky with colors, depending on which program you used, monitor, TV settings, etc. you can get weird results.
Check it out here, these are made in calibrated Photoshop, on a calibrated monitor.
You can try your colors here:
https://www.rapidtables.com/web/color/RGB_Color.html
The values you posted looks more "lime" to me than yellow.
213-235-57

213-235-59

These I have used when I wanted a more "yellow" color on my subtitles.
240-201-136

254-236-185

255-215-0

Kind regards,
varekai

Nice catch, I never noticed this. I can confirm slight changes in RGB (B actually) when exporting SUP to SUP.
SUP to XML/PNG export seems ok, but XML/PNG back to SUP suffers again.

[EDIT] You beat me to it, varekai. Will read.

Hi varekai, I think perhaps you did not understood the point of my post. My concern is that Subtitle Edit is changing is changing the color values after importing & exporting sup files, when it really shouldn't be affecting the color at all.

The subtitle I used as an example is taken straight from a DVD. I wish to edit the timing of it without altering the original color. Whether or not this subtitle is subjectively "yellow" or "lime" is not the issue.

Thank you for confirming. It seems like a bug, right?

Yep, it seems so. I also quick & dirty checked srt export:

srt --> SUP also has slightly off "B" value
srt --> XML/PNG seems ok

So, my guess would be there is something not 100% correct with SUP export B-value.
I'm sure Nikse will respond.

Subjectively or not, the value you posted you called it "yellow",
213-235-57 and 213-235-59
Which one of the images I posted looks yellow in your opinion?
Also the difference in these values are veery small, hardly noticeable...

Which one is which? Difficult isn't it, almost impossible, right?
Then use a colorpicker and find out...
Two free very useful apps (portable if you prefer) for colorpick.

Hey, never realized these existed. Very handy & direct for whatever's on-screen.
Thanks for pointing out.

In shortcuts, we can't add any shortcuts to each items of remove formatting. Would be great if we could do to remove italics for example.

What purpose does this discussion serve? Again -- I'm interested in how Subtitle Edit is altering color values of sup files.

I'm not interested in debating whether I used the most precisely correct color name to describe one example subtitle track. It is totally irrelevant.

Yes, I acknowledged from the very beginning that the change introduced by Subtitle Edit is very small. Does that mean we can't discuss it?

Yeah, I registered here so I could report this finding as my first post. You're the who wanted to have a debate with me about a color name, for some inexplicable reason. Now my post count is a problem too?

Perhaps it is you who needs to chill.

resolution, you may report your findings to Nikse555, maybe in PM.
In between you may test-run other colors to find if Blue offset stays constantly at +2 or moves with value,
this might help Nikse555 with troubleshooting

Is this something that could be tweaked, so that Subtitle Edit passes the colors through unaltered? Thanks!
SE will now try to keep colors (if possible) in latest beta: https://github.com/SubtitleEdit/subt...leEditBeta.zip

Does that work better?

Thanks for your effforts, Subtitle Edit is a true gem, one of its kind!
Couldn't do without it!

My humble opinion is that it is not worth wasting time on this so-called bug.
It is simply not possible to the human eye to determine the difference in these tiny color values on TV or the computer display.
However, if it is about commercial productions, such as photo printing, magazine art printing,
movie production, authoring and publishing Blu-ray and other multimedia,
then it is of course necessary with a near 100% correct color reproduction.
https://www.bbc.com/future/article/2...f-human-vision
Code:
Tried the beta
Created sup from srt, no color added in srt
For color used "blue"
0
255
255
Exported to sup

Used sup embedded in video (BD and mkv)
Used PowerDVD, PotPlayer, VLC and MPC-HC
VLC got the closest reading the others somewhat slightly different readings
1
254
255

Imported sup and edited time
Almost identical results.

Testings show SUP export keeping exact color values. From srt, SUP and XML/PNG all three seem ok now.
Thanks for the fix, Nikse.

BTW is there a solution in sight to the bottom offset issue mentioned earlier?

Examining SUP images with colorpick tool. I have been doing greyscales only in the 148 - 200 range.

Further having checked with different values for R G and B, I can confirm discrepancies (and not only for B values). Both srt to SUP export and SUP to SUP still suffer from it.

Which shows 2-254-255 in the colorpicker
