Answer: If the affected squash are in full sunshine rather than being shaded by foliage, that's probably why you are seeing the color change. If you can provide some shade from hot afternoon sunshine the squash should remain the correct color. As long as your plants are growing well, the change in watering should not affect the color of your squash. It's normal for growth to slow in mid-summer. Your plants are dealing with the heat in the best way it can - they are slowing down. Enjoy your garden. I hope you continue to have a terrific harvest!
