I am new to Illustrator so I am likely missing a step but when it comes to the fills, I like to choose a root color, make it Global then use the tint to give lighter variances of that color. The problem I have found is that when I am trying to find/make darker variances of the root color, similar to how I can do 50% tint to make it lighter, I have no idea how it is done. Is there a way to make it darker in percentages just as I can make it lighter with the Tint option?
As you see in Ref 1 and Eg 1 I made an attempt to find the darker shade of the root color by increasing the Key Color value to 100 while leaving the other CMYK values as is, and regardless of what percentage I put the tint thereafter, none of the lighter values matched the root color, by time it reached 60% it was already lighter and a dingy version of it. At 67% it was darker and no increment between them matched. So I am hoping that there is away to increase the darkness as seen in Ref 2, eg. 2 in which I can increase the root color values up in percentages until it is black (NB. the color stops in eg. 2 are not true color I just added colors as a reference).
So in short, I wish to freely decide on a root color for any of my art work and be able to go in both directions for lighter & darker shades as seen in Ref 3. The root color would be considered the middle ground. If that's not possible is there a way to find the darker shade of my root color so when a tint is applied at some point one of the percentages will land on the same color # as the root color?
thanks so much for any assistance.
