When you move on from basic editing skills to color correction and grading, one of the first tools you will encounter is a color wheel. This important standard feature in the world of color adjustment is much simpler to use than it might seem. This video explains the purpose of this tool, and shows why there are usually three of them, rather than one.
- [Instructor] A color wheel displays the red, green…and blue primary colors,…with the secondary colors you'll get by combining them,…positioned between them.…Combine green and blue and you'll get cyan.…Red and blue makes magenta.…And green and red makes yellow.…There's some interesting science…behind these color combinations…that are caused by changes to the wavelengths of the light.…But we don't need to worry about that,…we just need to know that these combinations are universal.…When making an adjustment with a color wheel,…the center of the wheel represents no adjustment at all.…
And moving the control puck out from the center…towards the edge means making a stronger and stronger…adjustment towards the hue you move towards.…Color wheels don't give you information,…they give you control over the appearance of your image.…Vectorscopes, which are described in another lesson,…do give you information.…Color wheels are commonly divided into three,…with one wheel adjusting color for darker pixels,…one for midtones,…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
