Tool-independent subtractive color layer configuration ツールに依存しない減法混色のレイヤー構成
It is a layer configuration to express a kind of subtractive color mixing.
Compared to normal layer compositing, it is possible to mix overlapping parts more vividly while drawing non-overlapping parts.
In addition, as you layer it, it becomes darker and does not become larger than the components at the bottom, so it becomes a relatively natural color.
configuration
Invert the lower layer once, overlay the layer drawn with the complementary color you want to use with additive luminescence, and invert the gradation again from above.
The amount of color mixing is adjusted by the opacity of the additive luminous layer.
Multiple additive layers can be stacked.
Once you get used to it, you can draw with complementary colors from the beginning.
principle
When RGB colors are considered as vectors, they are calculated by additive with the origin as white #FFFFFF instead of black #000000.
The bottom of the thumbnail is usually drawn by layer compositing, and the top is drawn with this color mixture.
Considering putting opaque pigments on paper,
Normally, layer compositing is a model in which pigments are laid on top of paper with the color at the bottom.
Color--●●●ーー
Paper-○○ー○○
This, on the other hand,
After putting the pigment on the paper, it is a model that additionally puts another pigment on the part that has not yet been mounted.
Color-●●●●●
Color○ー○ー○○ー
Paper-
It may go well with colored pencils.
一種の減法混色を表現する為のレイヤー構成です。
通常レイヤー合成と比較して、重なっていない部分も描きながら、重なっている部分はより鮮やかに混ぜる事が可能です。
また、重ねただけ暗くなり下部の成分より大きくなる事が無いので、比較的自然な色あいになります。
構成
下部レイヤーを一度階調反転してから、使用する色の補色で描いたレイヤーを加算発光で重ねて、その上からもう一度階調反転します。
混色量は加算発光レイヤーの不透明度で調整します。
加算レイヤーは複数重ねる事が可能です。
慣れれば最初から補色で描いても良いです。
原理
RGB色をベクトルと見做した時、原点を黒#000000ではなく白#FFFFFFとした加法で計算しています。
サムネイルの下は通常レイヤー合成で描いたもので、上がこの混色で描いたものです。
紙に不透明な顔料を乗せる事を考えると、
通常レイヤー合成は下部の色を紙とした上に顔料を敷き詰めるモデルです。
色ーー●ー●●ーー
紙ー○○ーー○ー○
それに対してこれは、
紙に顔料を乗せた後、まだ乗っていない部分に追加で別の顔料を乗せるモデルになります。
色ー●ーー●ーー●
色○ーー○ー○○ー
紙ーーーーーーーー
色鉛筆との相性が良いかもしれません。
