Color grading hints:

Color wheels - add color to shadows midtones or highlights.

RGB curves - control red green and blue channels independently.

LAB curves - unlike RGB LAB color space allows you to manipulate color channels separately from brightness component. This gives you much more creative freedom to play with colors.

Hue vs Saturation curve - make one color more vibrant than others or leave one or two colors only making the rest of the picture black and white.

Hue vs Hue curve - replace colors or color ranges with another color(s) by shifting their hue. I.e. you can change the color of the blue sky or green grass which can completely change the mood of your photo.

Hue vs Luma curve - adjust brightness of selected colors or color ranges. This allows you to brighten or dim parts of your image creating interesting creative effects.

Luma vs Saturation curve - adjust saturation of shades midtones or highlights.

Luma vs Hue curve - shift hue of shades midtones or highlights.

Saturation vs Saturation curve - boost saturation of unsaturated parts of your picture and decrease over-saturated areas to create evenly saturated HDR like pictures.
