What should you cover a confer tree (with needles, evergreen type) that has a brown color where you want to make it look greener.

Given the formulation of the DuraStripe Aerosol Paint I would not apply this material to a living tree, especially one that keeps its needles from year after year. I’m afraid the absorption of the material by the needles would be destructive to the tree.

The Aerosol Chalk product would be a better temporary solution, however we do not make this formulation in a green or turf green color.

What I might suggest is finding an arts and craft or hobby store, Office Max, Office Depot, Staples that sells Tempera paint. This paint can be used on many different surfaces and is removable. It comes in powder or paste. I would dilute the material to a one to one ratio and apply using a pump-up hand sprayer that is used by turf companies.

A bulk latex field marking paint product could also be used for covering the tree with little adverse impact. Also you consider a bulk chalk solution but at this time a green color is not being offered by Tru Mark Athletic Field Marker. You would apply the bulk paint and chalk using a pump-up or airless sprayer after being diluted.

Finally another product solution you might consider is a turf colorant. A turf colorant is typically used on dormant grass during the non-growing and dry seasons. This product is diluted typically to 10-20 to 1 ratio and has a longer duration then traditional turf paint. It can be applied using a pump-up or airless sprayer after dilution.
