what is the hardest spanish word

Although Mardle has answered your question beautifully, I'm going to unnecessarily complicate things by throwing in my two cents. 
There is no "hardest word" in Spanish, at least if you are referring to vocabulary. All vocabulary words are of different difficulty to different people. There are some extremely easy ones like "Negro (Black)" and "Vida(Life)" but I don't think that there are any true "Hard" ones. Some are just more difficult to memorize than others!
See, I told you that this was unnecessary!
Hi smith Welcome to the forum. Are you learning Spanish or English? If you can note on your profile an approximate language level we will know whether a mistake is careless or a lack of knowledge - eg learners of English need to know we use capitals at the start of Spanish/English etc. Your question has stumped me [I don't know how to answer it] The heading refers to colour - are you asking for the most unusual word in Spanish for a colour? Are you asking for something difficult to pronounce [unlikely as Spanish unlike English is logical as to pronunciation] If you can explain what you need to know I will try and answer.
'Electroencefalográficamente' and 'anticonstitucionalmente' are both very longs words and amongst the longest in standard Spanish (there are much longer science words, but these are specialist). 'Anticonstitucionalmente' is virtually identical to the French, 'anticonstitutionnellement', which is the longest word in standard French, and long though it may be, I actually encountered this word for real in a lecture in France. It means 'unconstitutionally', & I encountered it in a law lecture, so it's not inconceivable that you might encounter it in Spanish.
That said, it's not particularly hard to say, and even easier to recognise its meaning. It's also a rather ugly word, and I would imagine there are more eloquent ways of expressing the same sentiment.
In terms of pronunciation, I find 'desafortunadamente' rather hard to pronounce, but with practice I'm becoming better at it. Incidentally, the French equivalent, 'malheureusement' is one of my favourite words in French, and I find it very easy to say. In Spanish, I find it easier to say 'por desgracia', meaning much the same.
I suppose it's a personal question. Everyone will find their own areas of ease and difficulty.
For me, the verbs 'ir' and 'irse' are challenging, yet with perseverance they are becoming less so.
Buena suerte ¡!
