Here it is in WoB shades.

Lovely! I love anything done in the Wilsons of Bannockburn colours.

I'd glad those wonderful old shades are making a comeback.

About the shift of red to orange in "ancient colours", red indeed would shift to pink if it were made lighter in tint but stayed at the same intensity/saturation and hue. I can certainly see why the weavers would want to avoid that.

But red could stay the same hue (that is, the same position on the colour wheel) and the same tint (that is, relative presence of white) but be decreased in intensity/saturation, in other words become less vivid or strong (increase the presence of grey). It's like the red we see in "reproduction" or "weathered" colours. I wonder what "ancient" tartans would look like with the red remaining red.
