I've been sprouting my beans for three days now; yesterday I noticed some had developed a slight purple coloration while rinsing them, photo attached. One of them even went blue-ish, but there is no brown or signs of mold. Is this normal or should I worry?

Here's a picture of the sprouts:

The sprouts developing a purple tinge is fine, it's a sign that they were exposed to light - they will even start turning green if they recieve more light.

This is like with white asparagus: As long as the stalks remain completely covered in the soil, they stay white. If they start to break through the surface, they develop a purple tinge in a very short time.

See the picture below:
Some stalks are still white, some slighltly purple.
