Why does altering the color of an integral region result in a modification of the spacing in Latex?

edit

When the color of an integral region is altered, it typically involves using some form of highlighting or shading. These effects are usually achieved by adding additional formatting commands to the LaTeX code surrounding the integral, which can alter the spacing of the equation.

For example, some highlighting or shading commands may add extra vertical space above or below the integral, which in turn can affect the overall spacing of the equation. In addition, certain color commands can also affect the size of the integral symbol or the spacing between the limits of integration and the integral symbol.

Therefore, when altering the color of an integral region, it is important to be mindful of these spacing effects and adjust the surrounding LaTeX code accordingly to ensure that the equation retains its intended formatting and legibility.
