When you look at a flame at the base there is a blue flame. The blue part will take a cone shape with the pointed end at the top under the yellow flame (or light blue if its gas fueled like a beaken burner). The tip of the cone of the blue part of the flame (the inside cone the top tip of the cone) is the hotest part of the flame.

Colour tells us about the temperature of a candle flame. The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).

If the flame of a newly-designed most modern bunsen burner shows blue, white, yellow and red areas, i would put white as the hottest part, followed by blue, yellow and red. Just study the colours of the atomic bomb explosion on a video or the big stars in the Universe, and you will come to a more definite conclusion. What we were told about the flames of the bunsen burner decades ago, could be wrong.

A flame consists of two parts an inner blueish flame and an outer reddish orange part. The hottest part is the TIP of the blue inner flame

It varies as to how much oxygen is mixed with whatever fuel you are using and also what fuel you use is also dependent.
If you have a perfect balance of each, (propane lighters etc) then the outer core of the blue flame (just above the base to the tip) is generating the most heat. (if you look carefully at the center of the blue/violet flame you will see a slightly darker shade, according to the link below, the flame is hollow! Interesting! Anyway, The center of the flame determines how rich the mixture of fuel and oxygen is, the rest is sooty deposites.

Much depends on the supply of air/oxygen. If the flame is coloured this is because the fuel is burning inefficiently hence less heat is produced. So I guess the hottest part would be colourless/faint blue. My experience is that this is usually at the tip of the flame

If you are talking about a bunsen burner, it's just above the cone of air - about half way up.
Usually in a flame the place that is of a colour closest to white or blue will be the hottest. Red being less hot and yellow being less hot still.

the blue part of the flame is hottest

The hottest part of the flame is the "top" of an inner cone. This would normally be the bluish part, but different for each intensity of different materials. This is called molecular radical band emission.

The base of the flame. It can be a range of colors depending on how hot the flame actually is from red (cooler) to white (hottest)
