Well, that won’t be happening in the Pro-V lines anytime soon. It took years to get yellow released that performed as well as the white balls. Besides limited demand among Pro-V users, not likely it would increase market share.
Unlike tennis, even yellow golf balls have not gained wide acceptance. Based on postings, there is more interest in a couple of variants in the Pro-V lines than more colors.

It was several years before the ProV1 and ProV1x were optional yellow due to demand and impact to the production line to create multiple options. Unfortunately I believe you will be in the minority for wanting orange and it would not be economically viable for Titleist. Never say never but until then, enjoy the yellow versions.

I’m worn out from wishing, praying, and pleading for the yellow. Thankful for them and enjoying them immensely.

Probably wont happen.... But I did dye 2 dozen practice ProV1's orange. Worked well and made it easy to identify which balls were mine in the practice area. Used Rit Dye!

The only ball that Titleist makes in orange is the Velocity. A true distance ball at an affordable price.

I’d buy a box in a heart beat and put my white ProV1 on ice if they release an orange ProV1

Might want to check with your cardiologist to make sure you aren’t skipping any heartbeats. Titleist promotes the Pro-C lines for serious golfers (at any level). Other brands have use gimmicks to market their balls. From various decals to balls of 50/50 colors. Yellow is as far as they have gone in the Pro lines. It isn’t coincidence that colors and mat finishes are limited to Velocity and TruFeel lines.

Haven’t checked the DTC brands. But they are marketed to the general public. Titleist won’t be chasing those with the Pro-V lines.

Nothing wrong with colored golf balls, but I prefer white. Number one ball color on all tours.
