i'm wondering what is up with coloring that is added to e-liquids, i thought it was from the flavoring before but now that i am going with my own DIY blends i am noticing that the colors of the concentrates don't or barely show in the blend. so i figure that vendors are adding more coloring because most e-liquids. is there any point to this other than just appearance? it seems really silly to me to do that because this means people just end up vaping more junk that doesn't actually benefit the vapor or e-cig in any way. does any find seeing color in the e-liquid/tank/clearomizers to be more appealing? i guess i can see that mattering to some people, but me personally i prefer to not be vaping anything that is not necessary so the clear liquid i'm blending is much more appealing than pre-blended stuff i got before.
