These are not the default colors. In the options menu there is a Color Blind Mode. Options are None, Protanopia (Red/Green), Deuteranopia (Green/Red), Tritanopia (Blue/Yellow), and a Color Blind Mode Strength slider 0-100. Based on the color of the grass she hides in (which is normally red) it could be either the first two. The third option makes that grass green, not blue.
