Understanding RGB, Curves, and Color Adjustment Tools in Photoshop

Every color adjustment tool in Photoshop — Curves, Color Balance, Selective Color — operates on the same underlying logic: the RGB color model. Understanding how red, green, and blue light combine, and how tonal values are distributed across highlights, midtones, and shadows, gives you the foundation to use any of these tools with intention rather than guesswork.

Practical Tips

Key concepts from the video to apply directly in your editing workflow:

• Read the histogram before touching any adjustment — the distribution of pixels tells you whether an image is dark, bright, or balanced, so you know where to intervene.
• Use individual RGB channels in Curves to shift color in specific tonal ranges — for example, boost the blue channel only in the highlights to add a cool tint without affecting shadows.
• Use Selective Color when you need to adjust one hue without disturbing the rest of the image — it lets you modify brightness and color balance within a single color range.
• Think in opposites: reducing red adds cyan, reducing green adds magenta, reducing blue adds yellow — knowing these pairs helps you correct or grade color deliberately.
• Anchor points on the Curves line preserve tonal areas you don't want changed — place a point on the midtones before adjusting the highlights to keep the rest of the image stable.
