Here is the blue panel in my Book of Color study.

Picture of the supplies I used,

• Acrylic paints – soft body and fluid.  The cheaper acrylic color, Ultramarine Blue and Cobalt Blue had a significant purple hue to them.  Both are nice colors just not the blue I was expecting.  The Golden fluids were Teal and Manganese Blue Hue.  The teal is light and a beautiful tint of “Robin’s Egg Blue”, the Manganese Blue is dark with a bit of a grey undertone.
• Fountain Pen Ink – I pulled out a bottle of J. Herbin “Bleu Pervenche” ink and used a small brush to paint the color on.  WOW, this color is an absolutely beautiful turquoise color.  The color is saturated and stained the paper.  The box doesn’t state that it is waterproof, but I did lay down watercolor over it (after it dried) and it did not blend.  I love this ink.
• Daler Rowney Acrylic Ink – I chose Rowney Blue, a dark “ocean” blue.  You can see the strip on the lower left side of the page.  I like the color and wondered if I could have used a cosmetic sponge to push it through a stencil even though it is a liquid.
• Dylusions Ink Spray in Calypso Teal – Another beautiful shade of Teal.  The color, when sprayed, came out darker, but when I used a brush to push it around, the color was easily recognizable.
• Liquitex Acrylic Paint Markers – Brilliant Blue is a nice medium blue with a bit of green undertone.  The Cobalt Blue Hue is a darker shade, leaning towards Ultramarine blue.  I liked both colors.  I prefer to paint with a brush rather than the pen.  The pen tip leaves marks, like a marker does.
• Faber Castell Gel Sticks – love the creaminess and saturation of color.  I did notice that if you lay down too much, it is harder to get the color to spread evenly when wet.
• Caran d’Arche neocolor II – I chose four different colors of blue, two were purple (Ultramarine and Blue Lavender), one was  more grey (Light Blue) and the other was Turquoise.  Although I love the ease of laying down the color with these, I don’t like seeing the scribbles after I have added water and brushed them out.
• Cray-Pas Oil Pastel – Cobalt Blue Hue – like I did in my earlier studies, I only laid down a little bit and rubbed it out with a rag.  The color is a medium blue and stains the paper.  Since other mediums do not go over the oil, perhaps this should be applied in the last layer.
• Colored Pencils – I chose a range of colors in Faber Castell, Blick Studio and Prismacolor.  I liked all the colors but in particular the aquamarine, more of a green than a blue but blended well with the other colors.

What I enjoy about this panel is the variety of blues (the green and purple tones as well), still read blue overall.  I discovered that fountain pen ink is another great medium, not just for filling a pen.

The next panel is purple.  Hmm, I don’t see a lot of purple supplies.  This should be fun.

Cheers!
