Somehow, I inherited this project that comes with a logo, the CEO already has business cards printed with that logo on it, and as far as I’m concerned, the colors and design are non-negotiable anymore.
So far, so good.
The tricky part is that I’ll be working around that logo: web site, t-shirts, marketing collateral, etc. The logo consists of three letters in a space age font, and it’s simply attractive, because the previous designer (?) used a blue gradient:
dark blue not so dark blue even not that dark blue lighter blue light blue glaring blue light blue lighter blue even not that dark blue not so dark blue dark blue
And although I could sort of eye-ball the
middle of the roadblue that was used to produce the logo, I was wondering whether there is a better method for finding the base value of the blue gradient.
A gradient is simply a transition between two or more colors along a line. There is no “base value” or color. That said, I do understand your question, and I think you’ve already found the best answer; just eyeball what looks best for your medium (digitial, print, etc.) and use that. Once you’ve settled on a base color, then make sure you record it somewhere (like in a branding guide) and use it consistently.
Note: If you have the source file for the logo, and the gradient is a composite of several layers then it might be possible to pull out a base color of sorts. For examply I often do this in Photoshop:
