Investigation

This are some controlled values found in the dwg while using the method ReadCmColor()

Dxf values are in decimal | hex | bin

DXF { Code: 62 Value: 80 | 0x50 | 0b0101_0000 }
rgb = 0xC3000050;
rgb_bin = 0b1100_0011_0000_0000_0000_0000_0101_0000

DXF { Code: 62 Value: 150 | 0x96 | 0b1001_0110 }
DXF { Code: 420 Value: 1151726 | 0x1192EE | 0b0101_0000 }
rgb = 0xC21192EE;
rgb_bin = 0b1100_0010_0001_0001_1001_0010_1110_1110 //420 value

DXF { Code: 62 Value: 31 | 0x1F | 0b0001_1111 }
DXF { Code: 420 Value: 16564615 | 0xFCC187 | 0b1111_1100_1100 0001_1000_0111 }
DXF { Code: 430 Value: DIC COLOR GUIDE(R)$DIC 7 }
rgb = 0xFCC187;
rgb_bin = 0b1100_0010_1111_1100_1100_0001_1000_0111 //420 value

Bit 0x1000000 seems to be the true color flag
