The Color Picker allows you to easily adjust a color value for a color property in the Unreal Editor. You can adjust colors by RGBA (red, green, blue, alpha), HSV (hue, saturation, value), and Hex (ARGB). Alternatively you can select a color by clicking anywhere in the color wheel or by capturing the color under your mouse, anywhere on your monitors.

When working with the Color Picker, it does not assume a straight inverse gamma conversion from colors sampled on the screen using the Eye Dropper. Instead, sRGB is the assumed space all colors are sampled in, making sampling colors from Photoshop the identical version of the color converted into linear space. When transformed back into sRGB space, it will be the same color you saw in Photoshop.
FColor
and
FLinearColor
can also default to the sRGB space using a UPROPERTY meta tag of
sRGB=true
(or
false
), you can force a specific default checking of the sRGB checkbox.
Several places in Unreal Motion Graphics (UMG) now force this default since sRGB is the space UMG will be rendered in (on PC). Additional work will be needed on Mac where the final rendering space is gamma 2.2.
