While testing my GTX 1050Ti on CGA, EGA, TGA, the games just blacked out. No colour whatsoever. However VGA modes worked fine, as well as VESA mode in Duke Nukem 3D.
How's the color compatibility in the last generation cards, and the RTX cards?

Last gen cards dont have VGA or DVI-I/A, so it wouldn't make sense to implement old tech like RAMDAC or support for CRTs.
Does your 1050 have any analog output?
i386 16 ⇒ i486 DX4 100 ⇒ Pentium MMX 200 ⇒ Athlon Orion 700 | TB 1000 ⇒ AthlonXP 1700+ ⇒ Opteron 165 ⇒ Dual Opteron 856

Only a dual link dvi-d

Last Nvidia card with analog support is 980 Ti/Titan X Maxwell
I must be some kind of standard: the anonymous gangbanger of the 21st century.

Hmm that looks like it. Since 10 series it has all been DVI-D only. Also the VGA/DVI-I output on those cards were pretty broken anyway...
Btw why is VGA/SVGA/MONOCHROME still available on HDMI?

Backward compatibility is required for things like booting in legacy BIOS mode.
Some legacy commercial and industrial applications still might need to run from DOS (and other OSes), for example, and talk to a VGA compatible card directly, regardlessof the type of monitor connected to it. Prior to native analogue RGBHV being removed from cards, VGA compatibility typically worked on DVI/HDMI and analogue RGBHV output. Removing that VGA functionality would have made those essentially cards useless when booted in BIOS legacy mode (or on a UEFI motherboard when using CSM).
Cards that only support UEFI booting (no CSM) have no reason to support VGA hardware compatility (nor would they have a practical way to do it, as executing a legacy VGA BIOS would be required, and this cannot run on UEFI motherboards that do not have CSM support).
For many years I've found that Intel integrated graphics on laptops or motherboards has had way better support for old video modes than Nvidia/AMD/ATI.

Don't know about ATI. But at least for the last 10-15yrs that seems to be the case

Ironically, Intel iGPU graphics were among the first (if not the first) to completely drop support for VGA compatibility through CSM .
