Red and blue flame color collision

Quick answer：

Red and blue flame collision refers to a visual phenomenon where red and blue flames are combined or mixed, creating a unique and striking color contrast. This effect can be observed in various contexts, such as fireworks, campfires, or flame effects in visual media. The science behind this phenomenon is the interaction of different wavelengths of light emitted by the flames. Red flames typically result from carbon-based fuels, while blue flames are associated with oxygen-rich environments. When combined, the contrasting colors create a visually appealing effect.
