OK I give up. The texture map that I am using looks totally different when rendered in Lightworks. The map is yellow siding, when rendered, it's a nice shade of apple green. I have tried to adjust the values, but am pretty much guessing and trying to get the preview box the right color.
It also appears the preview box has no connection to what is rendered. Siding is yellow in the preview, green in the rendering.
This might be a taunt and a dare.
