Mac equivalent to iOS Colour Filters (Tritanopia) I have Tritanopia (Blue / Yellow) colour blindness.

In iOS I can use Settings > General > Accessibility > Display Accommodations > Colour Filters > Blue / Yellow Filter to boost the relevant colours on the display.

I looked around but apart from applications hacks and messing with monitor calibrations I couldn't find anything easy.

Is there an equivalent on Mac?
I've used the xSCope app to do this using their loupe tool (so it's not for full screen use) for several years and it's a workhorse of other design and measurement goodness. You might check out f.lux as well but that seems to be more bio-perception for decreasing blue hues on a circadian cycle that tracks sunrise and sunset.

I don't think this full screen feature is embedded in macOS High Sierra (yet) and it's not explicitly enabled on older Mac OS versions in as usable a format as iOS 11 does. Perhaps later in the year or next year this would come natively.

In the mean time, you could use a third party app or try setting a custom color calibration / display profile for some light correction. I don't think either of the above is as powerful as iOS accessibility, though.
