True Color Luminance adjustments possible? |
|
|
I am trying to work with the Luminance value in the True Color dialog.
Here's what I am doing by hand that I wonder if perhaps it can be automated.
Within the True Color dialog I enter some True Color number, say
132,154,174. The Luminance value now reads 60. Fine. I now want to get
adjacent true color numbers by simply increasing or decreasing the Luminance
value. I enter 57 Lum and then read and write down 122,146,168. Enter 54
and read and write down 113,139,162, etc., etc. I do this to make a list
for half dozen True Color numbers. Then I use that list as input values in
my little AutoLISP routine to create a sample printed color palette for
visually selecting final colors for a large plot.
I know of no way to address Luminance value under AutoLisp. Only True
Color.
