The RGB colour entries in Mac II's palettes are supposed to be 0 - 65535 but when converted to the conventional range 0 .. 1 by: newcol.red := col.red/65535 etc where newcol.red, green and blue are reals, it starts inserting negative numbers (possibly -32767 to 32767 or something similar). Can anybody think of a suitable assignment for going from the integers to the reals (and vice versa) apart from adding and subtracting 32767 etc. Thanks, S Cox UEA Norwich, UK swc@uk.ac.uea.sys
