The flame should be very pale blue (almost invisible) for heating strongly. This is achieved by opening the air hole fully.
Red brick; it is not a burning but a heating.

The clean flame for heating on a Bunsen burner is the blue flame. This flame has a well-defined inner cone and burns with complete combustion, producing a high temperature suitable for heating applications in the laboratory.
A blue flame is ideal for heating in a Bunsen burner. It is hotter and more efficient for heating compared to a yellow flame. Adjusting the air intake and gas flow can help achieve a clean blue flame.
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
The colour turns brick Red .
A heating flame, typically a blue flame, is characterized by a more complete combustion, producing higher temperatures for efficient heating. In contrast, a safety flame, often yellow or orange, indicates incomplete combustion, resulting in lower temperatures and visible soot. Additionally, a heating flame is more stable and focused, while a safety flame can be more diffuse and less efficient for heating purposes. Safety flames are often used in laboratory settings to prevent accidents and ensure visibility of the flame's size and intensity.
The blue flame on a Bunsen burner is used for heating because it produces the hottest flame due to complete combustion of the gas. This flame is ideal for tasks that require high temperatures, such as sterilization or heating chemical reactions.
luminous
You get and orange - yellow colour.
Yellow/Orange. The blue one is harder to see and hotter.
I suppose that the flame test was not applied to californium.
