Can reflector size affect LED tint?

[grnamin]

I have an XM-L2-U4-1A LED running in the 6200-6700K color temperature range. When I connect the light engine to the wide reflector of a Tain Nova Ti the beam has a greenish tint. When it's attached to a McGizmo Haiku head the beam color is cool white. Does reflector size play a part in beam tint?

No. Reflector coating and lens coating does.

Suppose the tint is highly depending on angle of emission out of the emitter (longer way through the phospohor at light leaving sideways, shorter way for light leaving upright). Then the angle at which the outer area of the reflector is collecting light (contributing most to throw, is it steep or flat-angle?), might be relevant?
A variation: This also might result in different tints for spot (steep edit: medium angle) and corona (upright angle).

.oO(I hope I haven't confused terms concerning angles and you get the idea...)

Thank you, Enderman and Sven. Reflectors are similar and both lenses are sapphire with anti-reflective coating. I tried without the lens on both, same results.
