Olive: [Feature Request] Color picking and remembering save location

[hyblocker]

Color Picker like this:

Pretty much, you choose a pipette and can choose from any color on screen. Its useful as you dont have to take a screenshot and open it up in an image editor, when setting the chroma key color (for example).

Remember the save location, so that you don't have to navigate everytime from the olive install directory to your save location.

Unfortunately the color dialog is platform dependent, and while most platforms provide a color picker, a lot of flavors of Linux don't.

Olive will probably need a custom color picker in the future anyway for a correctly color managed workflow.

Ok, didn't notice the color picker, but what about the save location?

a lot of flavors of Linux don't.

FTR, color picker work as expected under Debian 9.x Xfce.

a lot of flavors of Linux don't.

Is this a Wayland thing? I've been through Ubuntu (Unity, KDE, MATE), OpenSUSE (Cinnamon, KDE) and Arch (GNOME, KDE, XFCE, Cinnamon) and in all of them, Qt screen color picking worked properly.

This.

Great foresight, and indeed all of the pickers out there are more or less dumpster fires.

If a user is using an sRGB monitor, but delivering in rec.2020 (and viewing footage on another monitor) would the colour picker have to show (at least visually) out of gamut/colour space values? Ie: the colour picker would clearly let the user know that the chosen value on the sRGB screen is not displayable on the sRGB screen (but obviously displayable on the rec.2020 screen)?

NOTES:

• It looks like Katina & Mari allows colour picking to be piped through OCIO (which itself has a color_picking role in the config file) so that the colours chosen are transformed back to the working colour space (in order to give the matching colour at output)
• Mari allows the user to also select the color picker colour-space (rec.2020, rec709, defined in color_picking roles) however the displayed colours in the picker will always be shown as 0-100% of the monitors colour-space, and allows the percentage to go beyond 100% to describe colours not displayable on the interface monitor.

Try to keep issues to a single one. Given that the colour picker is given more depth of nuance in #914, I've flipped this request to solely be about save location.
