Blue stars are estimated to have an effective temperature of ≥ 30,000 K
Blue-white stars are estimated to have an effective temperature of 10,000-30,000 K
By contrast, yellow stars only have an effective temperature of 5,200-6,000 K.
Even yellow-white stars are only 6,000-7,500 K

Can a yellow star be bigger than a blue?
Yes, the color of a star is determined by its temperature, with blue stars being hotter than yellow stars. The size of a star is determined by its mass, age, and stage of life, so a yellow star can potentially be bigger than a blue star depending on these factors.
True or false Red stars are hotter than whittish- blue stars?
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
