Oliphant Mark 1B

I assume this type of tank dates from the last years of apartheid South Africa. What would the colors from that era be? Also, if Wikipedia is correct, the tracks had some sort of coating on them. What would they look like, assuming a newer tank?

The Mark 1B entered service in 1991. From what I’ve seen on the internet, it appears to have had 3-color camo of beige/brown/green.

Three color as stated above

or single color (very few tanks when the tank was first became operational)
