That's why people still, generally, see aircraft ... either from the ground or in the air.
The multi-spectral challenge has moved on from "painting it wiggly brown/green". There are so many dimensions to CCD its almost a science in itself.
Many lessons were learned in WW2, and subsequently ignored, other current ones may depend on technology ... but slapping paint on an aircraft [or things on the ground] can have complex consequences.
From my relatively limited work in this field, I vote for "Deception" as the others are
really rather hard to achieve.
