The discussion centers on the possibility of capturing lightning in different colors through photography techniques. It suggests that while lightning is primarily a black body due to the extreme temperatures it generates, it can exhibit color if the air is ionized, though this effect tends to average out. The vibrant colors seen in the referenced photo are likely due to the use of optical filters, Photoshop, or camera software adjustments to balance the unusual lighting. Additionally, variations in lightning temperature could theoretically produce different colors, but the broad black body curve means most colors are averaged to white light. Ultimately, the photographer likely employed various filters and extended exposure techniques to achieve the striking visual effect.
