No. 却 = but, yet, however, while, nevertheless, even though 而 = and, and so... "I love cats BUT she doesn't" vs "I love cat AND she doesn't". The nuances are totally different.

这个问题类似于“while" 和“but”的区别。但我很可能是错的，因为我也一直没搞懂它们的区别。我觉得而类似于“while", 展示对比两种不同的东西。but类似于“但是”，起到转折作用。

而 情感色彩相对平和 却 情感色彩非常强烈

they are interchangeable only on a few occasions. 却 always means a turn, 而 sometimes means a small turn, sometimes even not a turn. Think the difference between "but" and "while". so we usually say“ 我喜欢猫，而你喜欢狗”，we don't use"却“. "却” can be used in “我喜欢你，你却不喜欢我”（ps, 而 can be used here either)

意思是一样的，只是“却”比“而”转折意味更强一些。
