A little view point - Just pointing something out

1

Several challenges prior it was teaching me about Hex, rgb, and rgba
then when this lesson/challenge comes up, it wont let me solve the challenge with Hex.
it only lets me solve the challenge with plain text color words.
Just pointing this out, because its kind of hypocritical of the challenge to prevent this after it taught me to do it.
lol
