Why Red and Green color ink, is not used for writng Exams???

yeah the main reason is they use this ink colors for correction...so to differentiate between origianl contetns and correction..they restrict this inks to be used in examination

actually i love those two colors a lot but because it is the examinar who used to check our answer sheets with the red or green ink pen so we are not allowed to use those two colors for writing our answers. i hope u understood better. thank u.

Yes red pen always used by higher authorities and green pen is always used by gazated officer as per govt. i think ...perhaps the reason is this,,,,

i think that it is followed since ages. red is the colour which cannot be seen in dim light and it also spreads after u keep it for long. blue and black are dark colours and this helps to recognize the handwriting and it does not causes any strain on eyes. so probably i think that they r used in exams and not red and green. have a nice day.

because, they are traffic signal colours, so they dont want to confuse the children much, ha HA H LOL
