This semi pale yellow is with "Paper like material " - obviously it's not as thin as it should be for a thin material...
And this realistic one, with beautiful gradient is with the "Skin like material". 
Yeah, it’s because I have a little bit of the model under the plane. I tried to fix it by Flatten, but then the whole candle becomes unrecognisable or smaller parts just go way too much to the surface, so I’m not sure I know how to make the bottom part of the candle completely flat after sculpting at this moment of time but I think that was a very good remark of yours, I didn’t even notice I had the part of the candle under the plane. I’ll try to fix it with more practice in sculpting. Thank you!
Thank you, Martin! I still didn't get rid of that dark outline on the bottom of the candle but at least I know now how to cut the model in sculpt mode. 
Thank you! I’m currently on the 4.4, gladly will try the newest version!

I made everything except the fire, took it from a plugin. so, I took my time with this one. Mix the courses that already took in like Mesh Modeling, Digital Sculpting, Materials & Shading Lighting and some internet candle references from internet.
