Mercury has no real atmosphere and the temperature on the surface is from 80,000 to 700,000 degrees.
No, the entire sun would not appear black if it were the same temperature as a sunspot. Sunspots appear darker because they are cooler regions on the sun's surface, not because of their temperature alone. The sun would still emit light across other wavelengths, making it visible even at the temperature of a sunspot.
At the equator, the surface temperature on Mercury can range from -173°C to 430°C, while temperatures at the poles can plummet to around -193°C. The mean surface temperature is 67°C
The surface of Mercury can reach up to around 800 degrees Fahrenheit (430 degrees Celsius), which is much hotter than the average temperature on Earth. Earth's average surface temperature is around 59 degrees Fahrenheit (15 degrees Celsius).
The average surface temperature on Mercury is around 700 K (426.85°C). However, temperatures can vary greatly depending on the location and time of day due to Mercury's lack of atmosphere to regulate heat.

Mercury
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.

The dark area is known as a sunspot on the Sun's surface. Sunspots appear darker because they are cooler than their surroundings. They are caused by strong magnetic activity that inhibits convection and reduces temperature.
An area on the sun that is cooler is called a sunspot.
The temperature of Mercury's core has not yet been determined. The surface temperatures are very high because of the closeness of the sun.
Mercury has a high surface temperature and a low mass
