Colour Theory
Each oven has a certain hue and saturation (HSL model) that remains constant throughout the burn process. The hue and saturation depends on the location of the oven, but the correlation is not simple.
The colour map is split into rectangular blocks, separated by the lines x={0,4096} and y={-6144,-4096,-2048,0,2048,4096,6144}. Within each block, the hue will not change drastically, but the saturation does. In each block is a line upon which the saturation goes from 0% to 100%. At either side of the line the saturation changes gradually. Saturation = 100% are found at these lines. The hue changes gradually at all places within the block. The colours in a block is not correlated to the colours in other blocks, meaning that the change of colour over a block boundary is unpredictable, and most likely drastic. Close the block boundaries the hue cannot be trusted.
Full Saturation Line
The line of full saturation may be found once the saturation function is known. My best bet is that it can be fairly approximated using a second degree function:
saturation = a + bx + cy + dx^2 + fy^2 + gxy,
but the validity of this has yet to be verified.
Identifying the function requires 6 points to be known within a block, so in practise it is more feasible just to exploit the existing clay spots and hope for the best. Placing ovens in the corners of a block may give you an idea of where to search for the full saturation line. It is however possible that d and f will be constant, allowing for identification of the function with only 4 known points.
