Color charts[edit]

There is something wrong with color charts. I take a candle as an example. It has temperature, say 1000-1200°C, depending on the material and size. And candles have color from dark, orangish yellow to white-yellow. Not orange-red like it is on the charts. Other example: 2000K is 1727°C which is more than iron melting point. And iron at melting point is definitely not orange. Look at charts on welding and forging pages, they use it for their work. Eg. here And Planckian locus on chromacity diagram looks more in F than K.

One possible solution regarding your question can be the White points of standard illuminants. There's a difference between the visible color of a light source and the Correlated color temperature. So the display of the color temperature differs from the visible color too. --Angerdan (talk) 16:01, 16 February 2018 (UTC)

I agree about something being wrong with color charts. The chart in this section makes no sense, "Warm white" should be shown as warmer on the scale and "Soft white" as cooler but this chart has them the other way around. I'm pretty sure warm is warmer than soft and that's the order this company (which makes a very wide range of bulb color temperatures) has them in in their filters for their search on the left side of this page:,2701-3000 . It seems I can't edit this chart so am posting this. --— Preceding unsigned comment added by [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}#top|talk]] • [[Special:Contributions/{{{1}}}|contribs]]) )
