Random, with the preview on
Turn on Placement preview and a see-through copy of the next block shows where a right-click will place it, before you click.
Gradient
In Gradient, each row of the box is a step. Hold V and scroll to move to the next row between courses, here from calcite down through stone to blackstone.
Pick
In Pick, hold V and scroll to choose one block from the box, then place it.
Shapes
In creative, hold V + Shift and scroll to switch a block to a shape it comes in, like walls, so a mixed box can place full blocks and walls together.
Extra rows
A box can hold up to 16 rows. This one has six, fading from calcite and quartz through stone, tuff, and deepslate down to blackstone.
The palette menu
Tap V with a shulker box in hand to open the palette menu. Turn the palette off and every button but Power grays out, then on again to get them back.
The palette library
Load from the palette library shows your saved palettes, each with its own mix of blocks.
Load in survival
In survival, Load leaves the box as it is: real blocks where filled, faded copies with counts in the empty slots.
Random
With a palette box in hand, each right-click places a block from the box, picked at random by count. Here one box builds a mixed stone wall.
Repaint
In creative, repaint turns the block you click into the palette's next block instead of placing a new one.
How a palette box looks
A palette box is drawn open with its next block inside, in your hand and in third person.
