I'm familiar with converting RBG to Hex colors via the %colormac macro.
Here is the code I use to output the appropriate SAS colors. However, when I graph them it is clear it is not the correct colors. They are supposed to vary from yellow to red for the first six colors, and the last color is a standard grey. However, in some cases, the same color is output for multiple inputs (yellow and grey in this example). Is it possible to use exactly these colors in SAS?
%put %rgb (225, 210, 130) ; *this is a yellow;
%put %rgb(253,185,39); *this is a darker yellow;
%put %rgb(225,130,37); *this is a light orange;
%put %rgb(202, 82, 32); *this is a deeper orange;
%put %rgb(181, 18, 27); *this is a light-medium red;
%put %rgb(141, 27, 29); *this is a deeper red;
%put %rgb(191, 191, 191); *this is grey;
For grey and the first yellow, it outputs CXFFFFFF for both, which makes me wonder about the possible RGB color range.
Can these exact colors be used?
Thanks Paige. SAS needs 0-100 set of RGB.
Both the 0-100 and 0-255 sets of sRGB data represent the same sRGB standard. Notation in the 0-100 scale simply uses percentages of the 0-255 scale.
sRGB 0-255: 237-233-140.
To calculate the 0-100 value, simply use the absolute value of the decimal equivalent of the percentage of 255 contained in the 0-255 value, as follows:
R 237 = 237/255 = .929 rounded to .93; Absolute value of .93 = 93
G 235 = 237/255 = .909 rounded to .91; Absolute value of .91 = 91
B 140 = 140/255 = .549 rounded to .55; Absolute value of .55 = 55.
The resulting 0-100 value is 93-91-55.
We hope that you find this explanation helpful.
