Cream legbar egg changed color

My cream legbar started laying about 3 weeks ago...her first egg was blue - i added pic below - but now are bluish green....i thought a chickens first egg was the color it would be and not change or do they???

Egg color can lighten or darken, the base color can not change, but the hues can.

Thanks - it is almost a blue mint green now - still a very pretty egg I was just expecting it to stay the original blue.

Blue base shell will stay pretty much the same color.....but the brown coating, that makes a blue shelled egg green, can vary.
