ほどよく and とうてい

こんにちは皆さん、
私は夢十夜と申すの物語を読んでいる。
この文法がよくわかりません。


１。

真白な頬の底に温かい血の色がほどよく差して、唇の色 は無論赤い how does ほどよく modify the sentence?

Does it just put emphasize on 差して?

i.e...

The lower part of her pure white cheeks were tinged brilliantly with a colour like warm blood and her lips were naturally red ?

２。

とうてい死にそうには見えない。しかし女は静かな声で 、もう死にますとはっきり云った. does とうてい mean can't possibly in a negative sentence?

i.e

She can't possibly be dead as she doesn't appear so. however the woman asks in a clear soft voice "am I already dead"?

よろしくお願いします

1. Yes, it modifies the following verb. It's close to "moderately" but with a positive meaning - ほどよい is like "just right" (as in Goldilocks + porridge)

2. もう死にます is not "am I already dead" , and is not a question but a statement: "I am going to (soon) die". She does not at all look like she is going to die, but she still says "I am going to die."

Thank you that makes more sense now.
