Hi.  I haven't seen trhis mentioned in any of the replies to the original
note.  In V9, it's now possible to avoid the hex code when speciying
colors.  There is a suite of macros that become available once you submit
%COLORMAC.  The suggested cure to the original problem with..

%macro heatmap;
%do k=1 %to 90;
%let deg=%sysfunc(putn(%sysfunc(mod(360+92-4*&k,360)),z3.));
pattern&k value=msolid color=h&deg.7595;
%end;
<more SAS code>

was to use a HEX format...

%macro heatmap;
%do k=1 %to 90;
%let deg=%sysfunc(putn(%sysfunc(mod(360+92-4*&k,360)),hex3.));
pattern&k value=msolid color=h&deg.7595;
%end;
<more SAS code>

Question --- are the 75 and 95 hex code or should they be converted...

pattern&k value=msolid color=h&deg.4b5f;

Anyway, in V9...

%colormac;

%macro heatmap;
%do k=1 %to 90;
%let deg=%sysfunc(putn(%sysfunc(mod(360+92-4*&k,360)),z3.));
pattern&k value=msolid color=%hls(&deg,75,95);
%end;
<more SAS code>

There are a lot more color-related macros (%rgb, %cmy, %cmyk among them).
One catch is that if you have defined a SASAUTOS option, you need the add a
new location to keep %COLORMAC in the search path.

%COLORMAC is in the !SASROOT\GRAPH\SASMACRO directory.
