# Applying Changes and Color Space

This top-most panel contains the 'Apply' button and the color space selection buttons.

<div align="left"><figure><img src="/files/Z4o3X1xJHu4QuVKZfPR0" alt=""><figcaption><p>The 'Apply' and color space buttons.</p></figcaption></figure></div>

When you want to apply the adjustments to the image permanently, click the Apply button. Don't forget to do this before copying, printing or saving the image.

If hardware acceleration (OpenCL) is available, images can be processed in either Lab or RGB color spaces. Otherwise, processing will be done in the RGB color space only.
