Color system¶

In OmicVerse, we offer a color system based on Eastern aesthetics, featuring 384 representative colors derived from the Forbidden City. We will utilize these colors in combination for future visualizations.

All color come from the book: "中国传统色：故宫里的色彩美学" (ISBN: 9787521716054)

We utilized single-cell RNA-seq data (GEO accession: GSE95753) obtained from the dentate gyrus of the hippocampus in mouse.

we can get a color using get_color

Default Colormap¶

We have provided a range of default colors including green, red, pink, purple, yellow, brown, blue, and grey. Each of these colors comes with its own set of sub-colormaps, providing a more granular level of color differentiation.

Here's a breakdown of the sub-colormaps available for each default color:

• Green:

  • green1: Forbidden_Cmap(range(1, 19))
  • green2: Forbidden_Cmap(range(19, 41))
  • green3: Forbidden_Cmap(range(41, 62))

• Red:

  • red1: Forbidden_Cmap(range(62, 77))
  • red2: Forbidden_Cmap(range(77, 104))

• Pink:

  • pink1: Forbidden_Cmap(range(104, 134))
  • pink2: Forbidden_Cmap(range(134, 148))

• Purple:

  • purple1: Forbidden_Cmap(range(148, 162))
  • purple2: Forbidden_Cmap(range(162, 176))

• Yellow:

  • yellow1: Forbidden_Cmap(range(176, 196))
  • yellow2: Forbidden_Cmap(range(196, 207))
  • yellow3: Forbidden_Cmap(range(255, 276))

• Brown:

  • brown1: Forbidden_Cmap(range(207, 228))
  • brown2: Forbidden_Cmap(range(228, 246))
  • brown3: Forbidden_Cmap(range(246, 255))
  • brown4: Forbidden_Cmap(range(276, 293))

• Blue:

  • blue1: Forbidden_Cmap(range(293, 312))
  • blue2: Forbidden_Cmap(range(312, 321))
  • blue3: Forbidden_Cmap(range(321, 333))
  • blue4: Forbidden_Cmap(range(333, 339))

• Grey:

  • grey1: Forbidden_Cmap(range(339, 356))
  • grey2: Forbidden_Cmap(range(356, 385))

Each main color can be represented as a combination of its sub-colormaps:

• green = green1 + green2 + green3
• red = red1 + red2
• pink = pink1 + pink2
• purple = purple1 + purple2
• yellow = yellow1 + yellow2 + yellow3
• brown = brown1 + brown2 + brown3 + brown4
• blue = blue1 + blue2 + blue3 + blue4
• grey = grey1 + grey2

These colormaps can be utilized in various applications where color differentiation is necessary, providing flexibility in visual representation.

palette is the argument we need to revise

Segmented Colormap¶

When we need to create a continuous color gradient, we will use another function: get_cmap_seg, and we can combine the colors we need for visualization.
