Well I didn't really understand but I can give examples.
I tend to shade by using the dark colours first, and making sure you use the right colours is important, like some reds in the selection will not work well together, while others do.
Take the red guy in my picture for example.turbok1000.deviantart.com/art/…
I used DR6, DR5 and DR3 for his shading, and then a purple Spectrum Noir Blendable pencil to add dimention to the darkest parts of the drawing.
I start by putting DR6 down first, and then use DR5 to add a lighter shading before it, while only slightly going over the DR6 I placed down before. Then I use the DR3 to go over the whole area I want red and finally add a little more DR6 to the darkest shading to make it appear again.
This is my colouring method.
I used a blender to lighten where the sweat was so it was visible and used a white out pen to add highlights to the eyes.
If you're using black, I recommend using IG9 and IG8, since solid black would look strange on a detailed and shaded coloured piece.
I would also use either Deleter No.6 ink or Kaimei ink because it doesn't bleed if the picture is left for 24 hours after being inked.
The blender is important for removing mistakes, but you have to be careful, otherwise you'll end up ruining the colour, which I have done before, but managed to conceal with a lot of effort and patience.
I haven't done any grassy backgrounds yet. (I should really get to that.) So I can't give you any advice, and my style is pretty simple but detailed, so it would vary to many styles.
When I do hair shading, I do the same thing I did with the skin, but different at the same time. I tend to use five colours for the shading in hair and go from darkest to the second lightest, leaving a white line going through, largest at the source of light, and smallest where the shadow starts. When I've done that, I take the lightest colour and go over the whole hair, before adding darker shading to the ends of the hair because it will fade out otherwise.
Any other questions?
Oh wait! Also, I wouldn't use your markers for full on bold colour backgrounds, it would just be a waste of ink, if you are going to do backgrounds, vary the colours, or use scarce colours, maybe add a proper background will different shades so you don't waste the ink in one colour.
I hope I have helped.
