Are you asking if a yellow leaf is normal for the Scorpion plant or are you wanting to compare the new leaves on your plant to those of others growing the same variety?

If you are asking about whether a yellow leaf is normal then no, something is likely out of whack and a photo will be helpful. If you're just looking to compare, a pic will help also, but without ripe fruit little more than species will be known (annuum vs chinense etc). and even with ripe fruit there may be difficulty identifying the cultivar..
