Color Concentrate drop injection pics and question

[one-off baits]

I tried my first attempt at getting a color streak/vein with some clear belly injection baits. From what I remember reading a few years ago was that I'm supposed to put a droplet of color at the tip of the bait on top of the half I hand poured then inject the 2nd color. 

These didn't turn out like I had hoped. I had 2 out of the eight baits turn out, somewhat, okay.

I had those pearl brown  parts already hand poured days before I tried this so they weren't hot at the time. I just threw them in the mold and put a drop of blue on each one and then injected. Did that play a role in this? 

 

The 2nd photo is one I found on this site that I loved and was aiming for a similar drag of the color drops underneath my brown back color.  (even though I didn't use all clear)

Whats the best method for getting better streaks? Does the hand poured half of the bait need to be hot when the colorant drop is put on it? 

 

I don't know what this technique is called to search?

I guess this must be a closely guarded secret

Some colorants flow better than others.  If they're thick, you may need to thin them out some.  You can do this by adding some worm oil/scent or raw plastisol to the colors.

Okiedoke. I'll give it another shot soon. The colorant was a little on the thin side.

 

This time I'll also make sure the hand poured part is hot when I put the color drop on to also see if that helps. Last time I just put some pre-poured brown pearl backs into the mold when I started
