Colors

Color carries two separate facts. A node header says what the node does. A pin or wire says what kind of value it carries. Source-status stripes add a third signal in the Explorer without changing either graph meaning.

Data pins and wires

Var	Hex	C# aliases recognized
--bq-data-int	#00A000	int, long, short, byte, signed and unsigned variants, nint, nuint, and their System.* names
--bq-data-float	#569656	float, double, decimal, and their System.* names
--bq-data-bool	#880000	bool and System.Boolean
--bq-data-string	#00A8FF	string and System.String
--bq-data-char	#5C818E	char and System.Char
--bq-data-object	#800080	Reference types, interfaces, delegates, Unity objects, keyed containers, and named non-first-class types
--bq-data-struct	#9F649F	Value types, DateTime, Guid, Nullable<T>, ValueTuple, and common Unity structs
--bq-data-void	#808011	void and System.Void
--bq-data-default	#808011	default
--bq-data-wildcard	#9A9A9A	Empty or unresolved types, ?, null, dynamic, var, unknown, and unresolved
--bq-data-exec	rgba(255,255,255,0.70)	Exec wires and pins

A GET pill’s unlabeled helper pin uses rgba(255,255,255,0.45). A named non-primitive type falls into object/reference purple unless Round Trip knows it is a value type. Wildcard gray means the type has not been resolved, not “some object.”

Node families

Family	Token	Value	Used for
Entry / Exit	--rt-cat-entry-exit	#800080	Method entry, end, and return-family cards.
Flow / Conditions	--rt-cat-flow	#FFB400	Branches, loops, switches, break, continue, yield, and flow gates.
Event	--rt-cat-event	#8B0707	Method groups, custom event entries, and direct custom-event handler calls.
Dispatcher	--rt-cat-dispatcher	#6A0DAD	Event subscribe, unsubscribe, raise, and dispatcher definitions.
Default Pure	--rt-cat-pure	#095F19	Expressions, conversions, reads, builders, interpolation, and other value-producing nodes.
Default Impure	--rt-cat-impure	#0C0C42	Statements and side effects without a more specific family, including SET.
Call: this class/superclass	--rt-cat-call-this	#15B5A6	Calls to this class or a superclass.
Call: other indexed class	--rt-cat-call-other	#0B6E72	Calls to another type inside indexed source roots.
Call: external	--rt-cat-call-external	#566573	Calls outside indexed source roots.
Assignment variant	--rt-cat-assignment	#FF9F43	Assignment and declaration variants where distinguished.
Await variant	--rt-cat-await	#00A8FF	Await and asynchronous flow variants.
Try/catch variant	--rt-cat-try-catch	#CD6133	Exception handling scopes.
Using variant	--rt-cat-using	#2E86C1	Resource scopes.
Placeholder	--rt-cat-placeholder	#787878	Unsupported or placeholder nodes.

A node family answers “what does this node do?” Its data pins and wires answer “what value moves through it?” A call that returns bool stays in its call family; only its result pin and wire use Boolean red.

Source and draft status

Status	Token	Value
Modified	--rt-status-modified	#D29560
Added	--rt-status-added	#6FC491
Renamed	--rt-status-renamed	#5FB6FF
Deleted	--rt-status-deleted	#D4574C
Draft	--rt-draft	#8A6FD0

Modified, added, renamed, and deleted appear as source-status signals. Draft purple marks an uncompiled in-session change, including the Previewing your changes. banner.
