Wood-man --- I'm a little confused.
I have 10 humidors, and every one of them have a 'pinkish cream-colored' spanish cedar in them. The color is very consistant.
My closets, on the other hand, are lines with American Cedar (bad for humi's) ... and it has the beautiful reddish/dark pink swirls going through it, combined with the swirls of the lighter cream color.
I do know that Spanish cedar will vary in color depending on the origin and soil conditions. Generally it has a pinkish to red colored heartwood which darkens with exposure, to either a red-brown or red-purple tone. The sapwood is pink or white. The wood is usually straight grained, but can be interlocked. It has a fine and uniform texture.
Many humidors are lined with Honduran Mahogany, which is a yellow-ish cream color. this is what you may have in yours ...
