Hmm… I wonder if this is some kind of compounding of the same issue? As the 
snapshot captures with the incorrect color profile and then the imported 
snapshot is also impacted by the incorrect color profile. In your original 
example stack I imported a snapshot of the blue square and I get 60,153,240 on 
the original and 66,155,137 on the snapshot. Again if I choose the sRGB profile 
both the original and a new snapshot report the correct color for the graphic 
of 53,151,243 while the snapshot I took with the default profile now reports 
60,153,240.

There is definitely an LC issue. Try this:

1. Create new stack.
2. `import snapshot` and select something on your screen with a blue in it.
I used a Messages chat window.
3. Use digital color meter to check color of blue in actual window vs
snapshot. The snapshot is off.

Actual: 58,133,241
Imported LC snapshot:  83,141,233

Hmm… ok so I think I misread your original comment. Comparing Apple’s Color 
Digital Meter and LiveCode’s mouseColor does give the same results. Creating a 
swatch with the same RGB values in a color picker on a web page also results in 
the same RGB values I get from the LiveCode stack. I tried in chrome and safari.

Going in to the color profiles and changing to sRGB IEC61966-2.1 and the 
reported values are correct all around.

So it seems the default color profile in High Sierra isn’t right. I’m not 
overly sure what we can do about it. It might be that someone else on the team 
knows what to do or it could just be Apple’s bug to deal with.

Monte,

rereading yours and mine comments, i have to ask:

If Apple´s app Color Digital Meter shows the same values as LC´s function 
mousecolor, then  mousecolor is showing the correct values, isn´t it?
Or am i missing something?

I’ve tried tweaking a few things and I’m no longer sure the issue is ^ … it’s 
not seeming like this is going to be an easy fix over a Saturday morning coffee 
like I’d hoped ;-(

There may be multiple bugs. I created that test stack because snapshots I
take with LC show different colors than what I see on the screen. But my ui
colors also look different on 10.13 than on 10.12. So something is wrong
with color processing in general. Perhaps another example stack needs to be
created that imports a snapshot.

Yes of course it is I was just trying to determine where ;-)

From the looks of things we are using a function that takes a snapshot using 
the display color space then drawing it to our own image format using sRGB 
color space.

I´ve tested now with Apple´s  Digital Color Meter App.

And you are right. It seems the mouse color values are the correct ones. 

See screenshot http://d.qck.biz/vCD6n7 

But anyway. It´s a bug

If I enter the same RGB values into a html page that has a color picker then 
setup a send loop that checks the mouseColor I actually get the same wrong RGB 
value that LC reports. This says to me the issue is not with the display of LC 
controls but with the mouseColor function. More specifically it is likely to be 
with snapshot which is used by mouseColor.

Do we know if it’s the mouseColor returning an incorrect value or if it’s the 
actual control being the wrong color?

I am running 10.13 and can confirm this with my iMac 5K. The interesting part.
If i change the color profile in system control/monitor then the mouse loc 
values even change

LC displaying colors incorrectly in macOS 10.13

[Trevor DeVore via use-livecode]

Hi,

In LC 9 (haven't tested earlier versions) I'm seeing incorrect colors for
LC controls on macOS 10.13 but not 10.12. I filed a bug report with a
recipe + example stack and I'm wondering if anyone else can confirm my
findings. I'm not sure if it is software related or hardware related.

Here is the bug url:
