The C1 tooth color is the whitest and lightest “C” shade from the vita shade guide, but it is just one of many colors from the natural teeth color chart. This shade may look fairly white in color but it is actually a grayish color.

We will compare C1 tooth shade to all the other C colors as well as every other shade family. Prepare to be bombarded by images and videos of what this shade looks like.
What color is C1 tooth shade?

Below is the manufacturer instructions from VITA showing that the C tooth shades are grayish.

The diagram above shows you the difference between what the hue is and what the color is.
Yes, C1 is considered a white tooth color but it is technically a very light gray shade because that’s one of the natural colors of teeth.
FAQs
C1 is technically not white per say since it is more of a grey color. However, due to the value of this shade, it is often described as white by the average person.
This shade is certainly not considered yellow because if you naturally have it, no one would think you have yellow teeth. The average color for teeth happens to be A3 which is roughly two shades darker than C1.
Color C1 is not too white because it isn’t even the whitest natural tooth color (B1).
All of the tooth shades in the VITA classical shade guide are considered to be natural teeth colors. It is only if you whiten your teeth beyond these shade ranges that it becomes unnatural. These whiter unnatural colors are called the bleach shades.

Is C1 the whitest tooth color?
The shade C1 is the third whitest tooth color in the classical vita shade guide. In regards to the level of whiteness, it is eclipsed by B1 and A1.
The winner for the whitest natural tooth color belongs to shade B1.

The runner up for the second whitest shade is A1.

Therefore, if you personally have C1 colored teeth you shouldn’t ever think that they’re too white by any means. There are people walking around teeth that are 2 shades naturally whiter than yours.
Bleached shades
Just for your information, the classical vita shade guide is for the natural shade of teeth. Due to advances in teeth whitening, there is a level of whiteness which exceeds the vita color guide.
These extra white colored teeth are called the “bleached shades” or commonly referred to as the Hollywood whites.
C1 vs 0M1

As you can see in the image above where C1 is placed next to the whitest bleach shade 0M1. Clearly the 0M1 is the objective winner in who has the whitest shade of teeth.
C1 vs BL1
The BL shades are a part of a different tooth shade guide but it is commonly also used for veneers. Of course, the BL1 is the whitest one of its respective color family.

Is C1 a good color?
In our opinion, C1 is a great color to choose for your teeth whether you’re getting veneers or whitening them. It’s whiter than the average tooth color (A3) but it is still considered natural. It’s also not as white as the whitest natural color (B1).

If you whiten your teeth to the shade of C1, it will look very natural in your mouth. The same can be said for if you were getting veneers and wanted to change the color of your teeth. The dental veneers will also look very natural if you go with C1.
Typically it is when people go a lot whiter than the natural teeth colors that the veneers begin to stand out like a sore thumb. It looks glaringly obvious that you had dental work done.
Best color should match adjacent teeth
Despite everything that we’ve said above, the best color for is what the natural color of teeth in your mouth is.
If you were getting a single crown or single veneer, you’re not supposed to pick a color that you like or think that looks good. You’re supposed to choose a shade that seamlessly blends in with your adjacent teeth.
If that color is C1 then that is great but if it is a different color, you should choose that other color so that it can match. The goal is to have your entire dentition to be uniform in color.
Therefore, whether or not C1 is the best color for you would depend on the color of your adjacent teeth!
