What are the pros and cons of using black line art vs colored

>>2563353
colored lines blend in and are useful when you don't want a strong distinction between your rendering and your lines. Black lines usually look better when you use flat colors and shadows and / or heavier inking, where the lineart is the star of the image and rendering, if any, is secondary.

Some art styles only look good with visible and clear lines like mangas or comics. Take comics for example since they're colored, muscle definition and shading is probably one of the most important reason. You can use darker colors for shading but it wont seem as bulky/badass as clear black contours or big black shadows.

Now where colored lines comes in are when you take manga stylization which was created for black and white and decided to paint and render it more realistically. They are used to keep the style true to its nature without going too much into painting. Use too much black lines And it won't fit with painting, use no lines at all and it becomes 3D. So you just use colored lines to keep that traditional manga 2D feel except they blend with your painting.

It's literally what cell shading is for, same goal but in reverse, adding lines to 3D to give it a 2D feel. look up OKAMI or zelda wind waker.

Watch Disney's Sleeping Beauty (easily the best looking Disney movie). See this fish for a very obvious example. The pale blue lines give it a shiny appearance without clashing with the flat color style. The pale outline of the fat king's crown also gives it a shiny look, and contrasts with the faceted crown of the skinny king, reinforcing their rounded vs. angular appearances. Pretty much every scene makes good use of colored lines.

Use black lines when you want it to feel closer to a comic book style, or to at least give the user a heavy feeling that "hey this is meant to resemble something drawn by hand with ink".

Otherwise, use colored lines.

Don't think of them as lines. Think of them as contrast (As in photo realism got no lines). If you want to be stylish or simplify then black becomes a valid option.

There are no lines in the real world so stop using them you weaboo faggot.

Looks nice.

Are there any general guidelines for coloring your outlines?

Is it just a matter of choosing a darker version of the fill color?
