I've got a number of colors which I'm trying to reverse engineer from a binary blob.

I've narrowed it down to a small section of the file, with the following values:

c[(0,0,0)] = 0x000000000000000000000000000000000000000000000000 c[(1,1,1)] = 0xBF0E01554E8BA53F00000000000000000000000000000000 c[(2,2,2)] = 0x28669E4C5AC1C23F00000000000000000000000000000000 c[(254,254,254)]= 0x8026349E84EE584000000000000000000000000000000000 c[(255,255,255)]= 0x00000000000059400000000000000000000000000000193D c[(1,0,0)] = 0x77AD31D28614853FAC4E7111AF220640D52D4FEF829A0340 c[(0,1,0)] = 0x8B4660320FF59C3F5148F95093550AC032ACE29C3D4A0540 c[(0,0,1)] = 0xCE01487450BA6C3F281E4AB53579044013312C6B12540DC0 c[(255,0,0)] = 0xE01C58AC04464C40091768519039534082A2B8D49E065140 c[(0,255,0)] = 0x46F3DD4DDA665540BAD424C91DDF56C05E7592BA947D5240 c[(0,0,255)]= 0xD84DBD3AA1554140BF17BD2D09C85140F9DB813DD37859C0

I'm looking for tips in how to decode these strings to the corresponding color strings.

Worked it out - the colors are encoded using the CIELAB color model. They are represented as a sequence of 3 8-byte, little endian doubles, corresponding to the C, I and E components of the color.
