When drawing plans, elevations or design sections or surveys, it is very useful to have a wide palette of colors for the highlighter (Copic).
Really agree with this. I do wireframing and so I’ll outline main elements in black or gray, and I’ll often want to pop in some highlights afterwards. The garish highlighter colors are fine for…highlighting…but the value of that pen type is that it draws under the linework so I can be really quick with putting in the color splashes. Having customizable and more subtle colors would be a huge win for this.
