### The Pixel Toolbar

The pixel bar contains useful information about the current pixel that the mouse is located on, together with the zoom factor currently used to display the image.
The x1 box displays the current Zoom Factor.
Next to it are the X and Y coordinates of the current cursor location.
Afterwards comes the current pixel color value as an RGBA float or as 8 bits or as 8 bits hex.
Then comes the current pixel value in HSV (Hue, Saturation, Value). You can also select it to change it to display:

HSL (Hue, Saturation, Luminance)

CIE XYZ

CIE xyY

CIELab L*a*b

CIELuv L*u*v YUV Pal

YDbDr Secam/PalN

YIQ NTSC

ITU-601 Digital Pal/NTSC

ITU.702 Digital HDTV

Finally, the current pixel's Rec.709 Luminance (Y) Y = 0.2126 R + 0.7152 G + 0.772 B is also shown.
You can change it to display:

Lumma Y' = ( R + G + B / 3 )

Lightness L = (116 * Y ^ 1/3 ) / 100

The pixel toolbar can be toggled on and off by using the F2 hotkey.
