Halacha 1 specifies: 'yerakrak' (intense green) is the darkest green — like peacock wings or date palm fronds. This reflects the Torah's use of a doubled form (yerakrak) to indicate intensity.
Question 2
At the end of week one, a garment's blemish changed from intense red to intense green. What happens?
Halacha 1 explains: if the blemish changed shade (red to green or green to red), the blemished area is torn out and burned, a patch sewn in its place, and the remainder of the garment washed and declared pure.
Question 3
A garment blemish was torn out and patched. The blemish reappears on the patch. What is the ruling?
Halacha 6 states: if the blemish returns and appears on the patch (not just the remaining garment), the entire garment including the patch must be burned.
Question 4
Is a naturally colored (not dyed by humans) garment susceptible to garment tzara'at?
Halacha 10 states explicitly: colored garments do not contract impurity due to tzara'at — whether colored by human hands or by natural means (colored by heaven). Only white garments are susceptible.
Question 5
A garment has patches — some colored, some white. A blemish appears on a white patch and spreads to another white patch, with a colored patch in between. Is this spreading?
Halacha 13 states: if a blemish spreads from one white patch to another white patch, it is considered spreading even if a colored patch lies between them.
