There are other colored TC/PL lamps in the market (Colored versions of the Osram Dulux S and D and Philips PL-S and PL-D, and others).

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Nice coloured phosphors! Saw green Soviet "PL-S" once, unfortunately had no chance to grab it )

Into fluorescents and HV neon since I was 14.

Such a shame these never came into production. I remember walking past Tesla's Holesovice plant on a visit to Prague some years back. There were some interesting CFLs hanging in the windows of the derelict building.

We do not have to agree on anything to be kind to one another. The ability to be civil is available to everyone on earth, for free.

These were in production, till at least till 90's (when the complete Tesla Holesovice start went down), I still have few color DZ-9 (=PLS-9W), but unfortunately not working anymore.

With incandescents you have no other option than use the color filter.
With fluorescents, making only single color phosphor yield better efficiency, but bring logistic and consequently quality issues:
It need separate phosphor powder for each color, so separate handling from very early stage of manufacturing, what make the logistic more expensive.
All the phosphors, their suspension, coated tubes till finished lamps (that is most important, as it influence the all post-manufacture handling till final installation) are of white color, so very prone to accidental mix up, so the quality problems.
The BLB are a bit of less problem, as at least the finished lamp are deep blue/black in appearance, so a wrong lamps are easily to spot...

So it become way cheaper to just make an ordinary white lamp and coat it with filter gel. The separation even from the regular white production happen on quite late stage in the process, so before the gel is applied the lamps do not differ, so there is nothing to mix up, and after the gel application it become directly visible, what color it is, so easy to spot a wrong lamp at wrong place.
Indeed, the consequence is about 3x lower efficiency...

But some saturated colors you can not make without the gel filter anyway, because the mercury itself does radiate too much in green and blue...
