Phoenix is a constellation, not a single star. The constellation contains a very large number of stars and other cosmic objects which have no astrophysical relationship with one another. It is simply that they are located in such a direction, and are so far away, that they appear to move together. The different objects vary enormously in their colour and surface temperatures.
A constellation is an imaginary pattern in the sky formed by imaginary lines that connect several stars. The individual stars in a constellation have no relationship or association to each other. Every star in a constellation generally has a different color, temperature, size, age, and distance from earth.
The surface temperature of Denebola is approximately 8,500 degrees Celsius (15,400 degrees Fahrenheit). Denebola is a white main sequence star in the constellation Leo, and its high surface temperature gives it a bluish-white color.
The surface temperature of the star Capella in the constellation of Auriga, or the "Charioteer", is in the general area of around 5,700 degrees Kelvin, though there are more than one star in Capella. Capella Is the brightest star in Auriga and the sixth brightest star in the sky, not including the Sun.
Alnilam is a blue-white super giant star, with a surface temperature of around 27,000 Kelvin.
Red stars have the lowest surface temperatures.
yellow
The stars in the constellation Hercules vary in color from blue to yellow to red, depending on their temperature. The surface temperature of stars in Hercules typically ranges from 3,000 to 30,000 degrees Celsius.
Constellation's cannot be colors, but individual stars in a constellation can be. The Phoenix constellation is made up of 7 stars
The stars in the Pegasus constellation vary in color from white to blue, indicating high surface temperatures. The surface temperatures of these stars can range from around 6,000 to 25,000 degrees Celsius.

Cassiopeia is a constellation in the night sky, not a single star. The stars in the constellation vary in color and surface temperature. Some may be blue or white-hot, while others may appear red or orange.
Capricorn is a constellation, not a star. There are 104 stellar objects in Capricorn, and these vary greatly in their colours and emperatures.
Gemini stars can vary in color and surface temperature as they are a group of stars that fall under the Gemini constellation. Typically, Gemini stars can range from blue to white in color, with surface temperatures averaging around 7,500 to 20,000 Kelvin.
Scorpio is a constellation and not a specific celestial object like a star, so it doesn't have a color or surface temperature. It is a pattern of stars that form a shape in the sky.
Castor is a binary star system located in the constellation Gemini. The primary star, Castor A, is white in color with a surface temperature of around 9,221 degrees Celsius. The secondary star, Castor B, is cooler with a reddish hue and a surface temperature of approximately 5,828 degrees Celsius.
black
It sounds as if you are asking about a star - but there is no star by that name. Rather, there are several stars in the constellation Delphinus, with names such as alpha delphini, beta delphini, etc.
