ANALOGOUS COLORS are those which are adjacent to each other on the color wheel- the "Visual (Additive)" Color Wheel (as opposed to the "Mixing (Subtractive)" Color Wheel) was used in the making of these gradients.
There are 35 total Analogous Gradients- some are Whisper Light, some Bright, some Dark & some Pastels- all, as stated, are analogous, making them extremely soft & having smooth, delicate transitions.
