Actually I think it's better to color with solid colors and for shading you should use a colder variant of the color , for example if the hair is blue you would shade with a less saturated (and darker)purple (it depends on how saturated you want it though) and always remember how colors combine, like blue goes along with orange
What are ya talking your art is fantastic and so pretty!!!, I look up to your art
I also draw with my phone (I draw with my finger)

Y=mx+b is slope form
Y1-Y1=∆y
X2-X1=∆x
Is something to figure out the slope with two ordered pairs (doesn't matter which I think)
Y2-Y1=m(X-X1) is uhhh I don't remember the name I think this one was point slope
