If you want to change your lineart color on PaintTool SAI, the easiest way is by using Lock Opacity. Selecting this option protects the opacity of pixels in selected layers, or in simple terms, selects all the pixels in your lineart layer so you edit only that. Quick Note: Remember to keep your sketch, lineart, and color on separate layers to improve workflow and make future edits painless. This option works best on a separated linework layer. Step 1: Open the document you want to change the lineart color in SAI. Step 2: Locate and click on the layer in which your lineart is present. When lock Opacity is activated, a lock icon will appear on your selected layer. Step 4: Select your new desired color in the Color Picker. If you are looking to change a specific section of your lineart, the Pencil or Brush tool also works. Method 2: Using the Hue and Saturation Filter Step 6: Change the color of your lineart.

There are two color adjustment filters in PaintTool SAI: Hue and Saturation, and Brightness and Contrast. The Hue Saturation Filter can be used to easily change the color of your lineart in SAI. This method is optimal with an isolated lineart layer, as it will change the color of all the pixels in a selected layer. Step 1: Locate and click on the layer in which your lineart is present. Step 2: Click on Filter in the top menu toolbar and select Color Adjustments. Step 3: Select Hue and Saturation or use the hotkey Ctrl+U. Step 4: If unchecked, check the Colorize and Preview boxes. This will allow you to see a live preview of your edits. Step 5: If your original lineart color is black, first set the Luminance level above 0. Step 6: Using the Hue and Saturation bars, change the color of your lineart as desired. Step 7: When finished, press OK or hit Enter on your keyboard.
