1. Shade of red given by iron thiocyanate (5)
2. Orange with a second fruit growing at the top (5)
The answer to one of the above is 'blood'. But which one, and what's the answer to the other?
3. Had a triumphal march within blood lined hallway (5)
1. I think you are correct with iron thiocyante being "Blood". I know i suggested blood for number 2 but tht was without knowing that you lready had blood for the above one.
Have you checked to see if it is a setters error for number 3 and should be 6 letters?
// The navel orange actually grows a second “twin” fruit opposite its stem. The second fruit remains underdeveloped, but from the outside, it looks like a human navel—hence the name. Navels are part of the winter citrus family. They're seedless, peel easily, and are thought to be one of the world's best-tasting oranges.//
