Coloring by Model or Chain

Default initial colors for atomic models are tan, sky blue, plum, light green, salmon, light gray, deep pink, gold, dodger blue and purple (see color names):

 #1   #2   #3   #4   #5   #6   #7   #8   #9   #10 

If any of the above would exactly match the background, a different model color is used instead. For higher model numbers, an algorithm is used to produce colors distinguishable from the background and from other models. These colors are also used for coloring by model.

Per-chain molecular surface models are initially colored by chain ID, for example:

 A,a   B,b   C,c   D,d   E,e   F,f   G,g   H,h   I,i   J,j   K,k   L,l   M,m   N,n   O,o   P,p   Q,q   R,r 
 S,s   T,t   U,u   V,v   W,w   X,x   Y,y   Z,z   1   2   3   4   5   6   7   8   9   0 

Unique colors are generated automatically for other chain IDs (for example, those with two characters). These colors are also used for coloring by chain.

Similarly, there are default initial colors for volume data sets:

Element Colors

The default element colors are the same as the Jmol element colors. Pausing the cursor over a cell in the table below shows the corresponding hexadecimal color code. Element colors are used in coloring by element or by heteroatom.
