Adjust>White Balance>Kevin scale
Hello,
The color temperature slider in the White Balance is opposite of normal color temperatures. Normally, the higher the degrees Kelvin, the cooler the colors and the lower the degrees Kelvin, the warmer the colors. C1's Kelvin slider is the opposite (the higher the Kelvin, the warmer the color).
From the wiki page of color temperature: "Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (yellowish)".
Can anyone explain why C1's scale in the White Balance is the opposite of the normal way of describing color temperature?
Thanks in advance...

The slider "compensates" for the color temperature. It makes cool colors warmer and warm colors cooler. It works this way in every photo editing software package.

Hi Walter,
Thank you for the feedback. I figured there was a reason. Not that I agree with the software designers approach, I now understand the reasoning!!

It's not just the Capture One software designers that have the scale like that. It is the industry standard and similar to other software such as Lightroom or Affinity Photo, or many others. It matches what used to be the case before digital photography, when you could buy film balanced for different lighting conditions. So for example you could use film balanced for tungsten lighting, which would give you correct looking colours at a colour temperature of about 3000K. If you had used "daylight" film in those lighting conditions, your pictures would come out too yellow. And if you used tungsten film in daylight, your pictures would come out too blue.
So if you had taken your images in indoor artificial lighting, you might want to set the white balance slider to 3000K or so in Capture One (or in Lightroom, Affinity Photo etc) which would be the equivalent of loading your camera with tungsten-balanced film, which is designed to be used in light of about 3000K.
The light from a tungsten bulb is "warmer" in colour than sunlight - more "red-hot" than "white-hot" so the film, or digital WB setting, has to make it bluer to compensate.

Simple rule: Set Kelvin to match light at capture time.

Ian, Your final paragraph is correct. Tungsten film makes things bluer. Anyone trying to shoot indoors with daylight film using available light and no filter learns this quickly. However, I think you have the effect of daylight and tungsten film backwards in the paragraph above. Daylight film exposed indoors under tungsten incandescent lighting (like with a 100 watt incandescent bulb at about 2000K) looks yellow tinted because daylight film is designed to be exposed at about 5600K. The tungsten film is designed to shift the color approximately like a blue filter. The opposite is true for tungsten film outdoors, which shifts the color temperature upward to compensate for the lower color temperature indoors with tungsten bulbs, and so makes the print look blue tinted. This is just what you would see if you shot indoors with a blue filter and then forgot to take it off, outdoors.

Jerry C - you're right, of course. And I have now corrected my slip to swap "yellow" and "blue" in the last two sentences of the first paragraph.

The color of the slider shows what effect it will have on your photo. To the right will make your photo warmer, to the left is cooler. That makes it very easy to know which direction to go.
If the WB the camera chose is too low then your photo will be too cool (blue) and you will need to choose a higher Kelvin to make the photo neutral or warmer.
If the right WB is 5000 K but you choose a wamer light, eg. 2800 K then the photo wil not be warmer but cooler.
