Yes, in winter and early spring while the soil is very cold the leaf margins will have a red or pink tinge to it. In warm soil (or pot grown in greenhouses) the leaves are green/white varigated and no red/pink coloration at all. I think it comes out only when the roots are very cold.

The entire leaf will not turn red, but the leaf margin will have a pink or red glow to it.

This spring has been quite funny for our E&GE because they are green/white one day and next day turn pinkish again as temperature drops. In a few days I expect them to be fully green/white.
