Display the HDR Color Picker

With a 32-bpc image open, do one of the following:
In the toolbox, click the foreground or background color selection box.
In the Color panel, click the Set Foreground Coloror Set Background Color selection box.
The Color Picker is also available when features let you choose a color. For example, by clicking the color swatch in the options bar for some
tools, or the eyedroppers in some color adjustment dialog boxes.

Choose colors for HDR images

The lower part of the HDR Color Picker functions like the regular Color Picker does with 8- or 16-bit images. Click in the color field to select a
color and move the color slider to change hues, or use the HSB or RGB fields to enter numeric values for a particular color. In the color field,
brightness increases as you move from bottom to top, and saturation increases as you move from left to right.
Use the Intensity slider to adjust the brightness of the color. The color value plus the intensity value are converted to 32-bit floating point number
values in your HDR document.
1. Select a color by clicking in the color field and moving the color slider, or by entering HSB or RGB numeric values, as in the Adobe Color
Picker.
2. Adjust the Intensity slider to boost or reduce the color's brightness. The new color swatch in the Preview scale at the top of the Color Picker
shows the effect of increasing or decreasing stops for the selected color.
The Intensity Stops correspond inversely to exposure setting stops. If you boost the Exposure setting of the HDR image two stops, reducing
the Intensity stops by two will maintain the same color appearance as if the HDR image exposure and the color intensity were both set to 0.
If you know the exact 32-bit RGB values for the color you want, you can enter them directly in the 32-bit value RGB fields.
3. (Optional) Adjust settings for the Preview area.
Preview Stop Size Sets the stop increments for each preview swatch. For example, a setting of 3 results in swatches of -9, -6, -3, +3, +6,
+9. These swatches let you preview the appearance of your selected color at different exposure settings.
Relative to Document Select to adjust the preview swatches to reflect the current exposure setting for the image. For example, if the
document exposure is set higher, the new preview swatch will be lighter than the color selected in the Color Picker's color field, to show the
effect of the higher exposure on the selected color. If the current exposure is set to 0 (the default), checking or unchecking this option will
not change the new swatch.
4. (Optional) Click Add to Swatches to add the selected color to the Swatches panel.
5. Click OK.
