Question about Computers & Internet
I hate to be the bearer of bad news but a CRT monitor is probably quite old and past its prime. When movement causes colors to change, bad parts and loose connections are the culprit. Start saving your money, you will need to replace it with a flat screen monitor soon.

as you are electronics engineer so let us discuss technically.
as you are unable to see green colour means you might be seeing picture of magenta colour
red+blue = magenta
crt has got three cathodes
your two cathodes circuit is fine one ckt that is green cathode circuit is not working.
for that problem your will have to check

rainbow colour is normally due to magenatic effect on monitor
see that any magnetic thing is near monitor
if it is there remove it
.after that put off monitor for 15 minutes & then put on.see if any change is there
if there is any change is there wait for 2 or 3 days it will be ok.
if brightness is also less along with fad color then
check for video output section & crt electrodes for normal voltage.
it that is also ok then crt is getting weak,
please be in touch with me unless it is solved.
hope this will help.
