Royal Blue, bingo!
Actually, for many years, I used only Low Bleed IC, though back in the day I preached in general to have both cotton and low bleed in one's arsenal.
That was for a few reasons, low bleeds often cost more, sometimes possess a little less printability, and the possibility of ghosting on cotton. (though rarely seen)
Those differences have lessened over the years.
btw, even when I posted this, I had the screen loaded up with SF LB. I both wanted to see what the TSB community thought, and put it out there in general for everyone.
