View camera lenses have been color corrected for over a century. Chester Hill came up with achromatic color correction about 1729, since about the time, color correction for quality photographic lenses was a standard design and production requirement. Beginnings of achromatic color correction was used often in microscope optics:

Difficulty with the APO designation, it's definition can vary among brand and standards of what APO means. Know the APO designator alone does not define absolute color correction, color fidelity and all those expectations imposed on the APO designator. Late 1800's came Apochromatic microscope objectives using natural Fluroite crystals.
"After designing, testing and selling many different apochromatic lenses I can state this: There is no "definite" line where a lens becomes "apochromatic" in the world of commercial apochromatic lenses."

IMO, save your $, APO designation alone is not an assurance of excellent color fidelity and color reproduction.

What Bryan and Bernice said...
But buy an apo lens if you really think that will improve your images.
I read here on the forum, (must be true) that any sharp LF lens even before color had to resolve color well just to be sharp at the useful wavelengths

Precisely, based on an awful lot of color transparencies burned/processed and dialing in the entire color transparency process, APO is more marketing than actual substance. Add to this the real world of optical design folks as mentioned in post#12 tell pretty much what and how APO is used as a marketing ploy.
No surprise that a rapid rectilinear from the early 1900's does good on color as it is color corrected well enough. Keep in mind one of the classic LF lenses the Dagor dates back to before 1900 and it's color rendition on film is more than good enough.

Thanks for your comments.
Finally I will use my current lenses and I will see the results. There will be time to decide later.

MC is not necessarily related to color rendering; sometimes it has been used to fine-tune that kind of property; but many single-coated lenses are just as good in terms of hue reproduction. Nearly all modern post-60's view camera lenses are very well color-corrected. Apo is related to something else - precise alignment of different wavelengths of color for sake of high reproduction standards, or a high degree of enlargement. Since you're starting out with large format film, it probably won't need a lot of magnification in print. "Apo" seems to be a term partially abused for marketing purposes. Again, basically a non-issue for general photography with any relatively modern lens. Focal length is yet another topic, related to what kind of perspective you like: wide, slightly wide, normal, somewhat longer, long narrow perspective? It can be hard to decide until you experiment some. What kind of images do you mostly have in mind?
