Disclaimer: I have never skinned a cat; I've never tried. I have never looked at my cat and wondered what she'd look like sans-skin. Where in the heck did that phrase come from anyway?
Anyway... back to coloring.
I color in the way that makes the most sense for me:
I work from dark to light
I rarely use markers from the same number family
I usually use two stroke patterns
I underpaint or overpaint shade colors with gray, purple, or blue markers
I rarely highlight with markers
I add details and texture with colored pencils
And these are the methods I teach in my classes.
But here's the thing- I don't expect my methods to work for every student.
You live in a different body than I do. Your muscles move your hands and fingers differently than my muscles do. Your eyes see things differently; your brain processes information differently. We have different styles, preferences, and most importantly, we have different goals for our coloring.
There is absolutely no reason to assume that we should color the same way.
I find that about 1/3 of my students require something different. Maybe we change their grip or the stroke direction. Maybe we adjust the color palette, the number of passes, or the order of passes.
Of the remaining 2/3 of students who do closely mimic me, every single one of them will take my method and slowly modify it over the months and years as they perfect their own unique technique.
Millions of cats...
A good teacher will show you more than one way to do something. A great teacher will watch what you're doing and tailor solutions based upon your unique situation.
Ultimately, the goal isn't to learn THE ideal technique, it's to find YOUR ideal technique.
You're a unique person, why would you assume that your ideal technique would be right off the shelf (or straight off an internet tutorial)?
