Change the color of the AE layer

Quick answer：

To change the color of an AE layer, you can use the 'Color' property within the layer's settings. This property allows you to manually adjust the hue, saturation, and brightness of the layer, or you can use the eyedropper tool to sample a color from the image. Additionally, you can apply a solid color effect to the layer, which can be adjusted for color, opacity, and blending mode.
