3 Adjust Yl&G Mask Range.

Adjusting [Yl&G Yl Level] and [Yl&G G Level] may also affect the I-axis (color close to the skin tone). When [Yl&G Yl Level] is increased, the skin tone becomes slightly more yellowish. On the other hand, when [Yl&G G Level] is increased, the skin tone becomes slightly more greenish.

Adjust [Yl&G Mask Range] if you want to increase YI&G toward yellow and green without affecting the skin tone. As illustrated in the chart below, [Yl&G Mask Range] adjusts the gray area from the R-axis, which disables the [Yl&G Yl Level] and [Yl&G G Level] adjustments.

Increasing the [Yl&G Mask Range] value widens the masking range. By doing so, the effect on the I-axis (color close to the skin tone) due to adjustments of [Yl&G Yl Level] and [Yl&G G Level] is reduced. However, this also reduces the amount of correction by [Yl&G Yl Level] and

4 Adjust the hue.

Adjust the hue based on the R-, G-, and B-axes.

As illustrated in the chart below, increasing the value rotates the hue in the anti-clockwise direction on the vector scope, with the respective axes as the center. Decreasing the value rotates the hue in the clockwise direction.
