Meniscus.
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
If the colored liquid is opaque (you can't see through it) you can't see the bottom of the meniscus. If the liquid is like mercury, you can't see through it but it doesn't make any difference because the meniscus is reverse from that of water. You read the top.
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.

The medial meniscus is more likely to be injured than the lateral meniscus due to its attachment to the medial collateral ligament (MCL), which restricts its mobility and makes it more susceptible to injury during twisting motions of the knee. Additionally, the medial meniscus has a C-shape that makes it more prone to tears, especially during activities that involve rapid changes in direction or weight-bearing. The lateral meniscus, being more mobile and less tethered to surrounding structures, often sustains fewer injuries.

A graduated cylinder or a buret must be read at the meniscus, which is the curved surface of a liquid in a container. Reading at the bottom of the meniscus helps to minimize parallax error and ensures a more accurate measurement.
The meniscus will be more obvious in a cylinder filled with oil. This is because oil has a higher viscosity and surface tension compared to alcohol, leading to a larger curvature at the liquid-air interface of the meniscus.
