These fields can be edited like any other parameter on the Color page. Even though these values
display two decimal places of precision because of space restrictions in the interface, they really
contain three decimal places of precision since these are floating point operations; you just can’t see
the third decimal place.
To edit YRGB values directly:
– You can double-click on a field to edit its value numerically.
– You can insert the text cursor next to a value in this field, and use the Up and Down Arrow keys to
adjust the value one digit at a time.
– You can cut, copy, and paste values among fields.
– You can click on the field and drag left or right to adjust its value with a virtual slider.
The number fields for each Color Balance
Control and Master Wheel are editable.
Shared Adjustment Controls
The three modes of the Primaries palette also share two strips of controls for making more specific
adjustments to different aspects of the image, such as Contrast, Saturation, Hue, Highlight retrieval,
Color boost, and so on.
Like most parameters in DaVinci Resolve, clicking and dragging a parameter’s name or value to the left
or right lowers and raises that parameter with a virtual slider, while double-clicking that parameter’s
number lets you edit it numerically, and double-clicking that parameter’s name resets the parameter to
its default position.
The top adjustment controls
– Temp: A specifically constrained Gain color balance adjustment that lets you adjust the image
along a warm/orange to cool/blue axis corresponding to the naturalistic spectrum of color
temperatures used for lighting. Raising this parameter performs a Gain color balance adjustment
toward orange, while lowering this parameter to a negative value performs a Gain color balance
adjustment toward a blue/cyan split. 0 is unity. The range is –4000 to +4000.
– Tint: A specifically constrained Gain color balance adjustment that lets you adjust the image along
a magenta to green axis corresponding to the unnatural spectrum of color temperatures found
in artificial lighting sources such as fluorescent and sodium vapor lighting fixtures. Raising this
parameter performs a Gain color balance adjustment toward magenta (sometimes referred to as
“minus green” to correct for fluorescent lighting), while lowering this parameter to a negative value
performs a Gain color balance adjustment toward green (“plus green” to correct for other kinds of
lighting). 0 is unity. The range is –100 to +100.
– Contrast: The Contrast parameters let you quickly narrow or widen image contrast about a
user-definable pivot point. Regardless of which mode you’re in, these parameters are identical.
Contrast and pivot can also be adjusted using the DaVinci control panel via the CONTRAST and
PIVOT knobs on the Center panel’s default page, regardless of whether you’re in Lift/Gamma/Gain
or Log mode.
