Cotman Vs Van Gogh - My Favourite Student Grade Watercolours 

Me too 😂

When Oto Kano waves I wave back at her. 😂 I also wave at my villagers in animal crossing. 🤷‍♀

I think so too! I enjoy using both. ☺️

You are so welcome!

True, I have a palette containing both brands and use depending on what I'm painting 👌🏽

They really aren’t bad considering the price difference from the better makes. Love Cotman Cerulean though, might try that! ❤️

I've tried a couple of Grumbacher colors. They seemed to be good quality.

I love grumbacher academy, especially with staining colors because they go on vibrant.☺️

Thanks for watching!

🥳

Yay indeed 😄

@awatercolourist Congrats, friend. 👏 I'm about 5 hours late. 😞

@@TracyIndy one day, one day you’ll have your moment in the sun 😊

@@awatercolourist 🤣 🌞

Yes!

Yay!😂

I just saw your reference to the Baohong cotton paper!

Doesn't make much difference to me. What do you think?

@@JayNathanWatercolor Makes a huge difference to me. My first experience was with PY42 (Camlin), that time I had no idea about pigments or such, and remember it feeling extremely overpowering. (Similar to phthalos, the opacity, covering power scared me) and I didn't use it much. - Next experience, White Nights, by this time I have a basic idea about pigments, and I like "natural things" so I opt for their PY43 version. Instant realization about how different these pigments were. Similar to Lazurite vs. Synthetic Ultramarine. The PY43's were easier to handle (like Cobalt Blues), granted they got used more than PY42's, but they surely felt natural (like I felt like I was working with actual dirt than processed dirt). - Recent experience, Lukas PY42, reminded me of my experience with Camlin, by this point I think I've learnt to control it, but all things considered I still like PY43 over PY42 just because it (lol) "feels" natural.

BTW if you visit the UK, do hit me up bud! Should be fun hanging.

@@jalsiddharth I know you’re not asking me, but I think PY43s are less opaque and how low tinting strength…I don’t hate that, but I love opacity so it upsets me.

Nope

It's definitely cheaper where I am. I don't know if it's cheaper everywhere though.

@@JayNathanWatercolor Of course, price is location dependent. I'm in the EU so Cotman and VG are comparable. I have the whole range of colors from VG but only a smaller range from Cotman. VG has a 100 years light-fastness guarantee under museum conditions. Idk, I may be biased but I like VG better, I always recommend that for beginners. 😀

Cotman is cheaper in the US, and much easier to find than Van Gogh.

Late answer from a pigment nerd. Pigment chemistry is a bit complex, and pigments of the same pigment code can vary quite drastically from brand to brand, and natural pigments such as lakes or minerals can differ from batch to batch. Pigment scientists can sometimes find a way to “tweak” a color. My favorite example of this, because the difference is so dramatic, is Pigment Violet 19,- where you can go from the brightest hottest pink imaginable to almost a wine purple-both PV19 though, reason being is this particular pigment has different isomers (alpha for pink, gamma for purple) so by tweaking which isomers are present in a mix, you can change the color. In some cases, like phthalo blue, you can chlorinate it in the presence of oxygen and get phthalo green blue shade (PG7), where as if you do it in the presence of oxygen and bromine you get pthalo green yellow shade (PG36). What humans perceive as color is really the occipital lobes interpretation of the energies released by the transference of electrons from their ground state. PR101 is an iron oxide, so if you manipulate it by heating it, changing hydration states, etc. you fundamentally change the color because you change the electron configurations- but the pigment code doesn’t necessarily differ. TLDR; Pigment scientists can sometimes manipulate the electrons in a pigment in various ways to get different colors from the same pigment.

Different chemicals added change a color. Sometimes the precipitate (the pigment you see and is insoluble in water unlike a dye) is left in heat longer like with burnt siennas vs raw siennas. It is basically a synthetic iron oxide. Other times a chemical is added to change hue like Ultramarine Blue (PB29) vs Ultramarine Violet (PV15).
