Correct color for spanish leo2a4?

[Wyrmshadow]

Below is the reference pic I used. Is it even right??

The colour codes are correct, but the colours themselves seem to have been adjusted to allow the details to be seen.

Those instructions give the standard Bundeswehr-camo in RAL colours Teerschwarz, Lederbraun and Bronzegrün. Apparently that's what their Leo2A4s use.

I think their Leo 2E (2A6s) use an overall green which seems to have a much more olive tint.

You are right. AFAIK, Leopard 2A4 were just rented Bundeswher machines used to begin with training, wearing original german scheme. Definitive Leopard 2A6E are olive drab.
Markings seem to be correct.
