- so the right way to do this is a bit advanced and time consuming you have to unwrap your model in a weird way and then manually draw the outlines and texture yourself.

-which if you want my opinion if you working on a game or animation project and you get paid you should do the advanced way and draw everything manually BUT.... since this guide target audience is beginners we are going to use the easiest ways.


- - i assume you know :
1- how to work with hotkeys
2- how to work with blender environment
3- how to work with shader editor
4- already have model (if you want to practice with me)

STEP-1

1- add new material to your model.


2- and remove the connection between them.

3- now add a shader to RGB node and attach them like me.

4- after that add a color ramp and connect it like me.
5- put it into constant mode and start working or adding colors to color ramp and experiment with the setting until you get something you like.


STEP-2 : outline


-now lets give it outline as well i made i guide showing you 4 method of making neon light.
the last method is about outline.


but since i have nothing better to do im going to show you how you can make outline for this as well

first add solidify

flip the normals

switch the material offset to 1
go back to the material tab and add new material

add new material and delete the principled BSDF

and add emission

and set the color you want for outline
enable backface culling
DONE

this one is good when you have texture for your model

now this is ciri


first im going to create a material for the face and set the surface to TOON BSDF


remember that you have to unwrap this as well

after this we are going to add the face texture as well


now to see this you have to be in render mode

and you need a light source as well

sun light sources is the best for this

add one sun light

now with the size you can control the toon bsdf
you can also use the smooth
