So I tried your eye tutorial. I have some questions if u dont mind.
I assumed you made one cyan layer, copied that layer and made it yellow right? cause I dont see any new lines in the second picture of the tut. this is what I did atleast, and I got a similar result (green). I then copied the layer (cyan) again and made it magenta (layer set to darken again). My picture now went grey. not purpulish like yours. did you do something else?
I worked on the colors using Hue, saturation and lightness. I messed around with all 3 on all the seperate layers. It didnt really change things, the end color stayed very blend.
Your eye also has a very defined iris, mine didnt have that at all. I added a touch of yellow.
it was fun to do. I hope you dont mind me posting this pic in your thread, no harm intended, I just would like some extra info in what you did and how I can do that.
No it's fine! Critiquing is still practice for me I don't mind at all. First off, the tutorial I made was describing a coloring technique and assumed the viewer already understood eye anatomy. While I will get to the coloring, there are some things you should know about eyes before we start.
First, eyes are basically jelly-balls encased in square-edged skin flaps. While your drawing clearly shows you've noticed details of how to portray this through looking at other works, it seems you've never been outright told that. For instance, because of where you've chosen to place the catch-lights (the highlights in the pupil and waterline) the shading of the ball and the skin surrounding should follow the logic of where you've placed your light source. If you aren't using a reference, you really need to understand light and where yours is coming from to make it work. For now I suggest doing what I did: take lots of crappy photos of yourself or other victims doing whatever it is you need with whatever light source you need. Now for eyelashes: they are placed on the outside edge of the waterline. You placed them on the inside edge on the upper eyelid, which I'm pretty sure is a very real and painful medical condition that we do not wish to plague your future eye images with. In real people, eyelashes tend to be pretty wonky. Many different lengths, unevenly spaced, shooting off in different directions, tapering off at the tips (they don't actually taper, it's a pigmentation thing), and more on top than bottom by a long shot. If you are drawing a person wearing an Ardell's fringe than go to town making the straightest blockiest chunkiest lidhairs you please. Oh, and look at tear ducts for a while before your next attempt.
Okay! Now for coloring. To answer your first question, no, I didn't just copy each layer although that idea has now become an exciting future experiment for me. The idea is color mixing. Think about the color wheel for a mite. Let's say you are outside painting a tree but you're only got red, yellow, and blue watercolor paints to work with. First off, you want to do a wash for the green foliage. You need to see the color you want and deconstruct it. Well, remember that green is yellow and blue, but this tree is definitely more of a yellow. So you put down a strong wash of yellow and a weak wash of blue over. This tree is threatening to strip naked for autumn though, so you put a very weak wash of red to dull it down. Since red is the complementary of green, it will take the color into muddier territory. Skin is the same way. Since blue will be the opposite of the yellow/orange/red undertone most people have, you need to lay it down where you plan for shadow to fall, and since this is an eye, the black hole known as the pupil. Because we're bein' digital, those three change to CMYK format. That is why I start with a cyan wash when painting skin. Then yellow, a color most of us have in huge quantities. I was shy in adding yellow at first which is why my image was leaning purple. In contrast, yours became greymudland because you were simply copying and changing the hue from layer to layer rather than discerning the amount of base color each target color had and adding accordingly, so you had relatively similar amounts of each.
I will stop myself here on the off chance your eyes aren't bleeding yet.
