String Painter V2

String Painter V2 is the version of StringPainter the first one should have been. Same idea - derive a hex color from a seed - but it adds a count input so you can batch out a whole palette, an optional random_min/random_max range for the random mode, and the killer feature: a used_seed output that tells you exactly what produced each color. That last bit is the difference between "random colors" and "random colors I can reproduce tomorrow."

How it works

For each of count iterations it does the same seed→hex masking as V1, then:

• increment mode uses your seed, formats it, and bumps self.seed = (self.seed + 1) & 0xFFFFFFFF - so a count of 5 walks five consecutive seeds and wraps at 32 bits.
• random mode draws each value from random_min to random_max (defaulting to the full 32-bit range).

Both the hex strings and the seeds that produced them come out, comma-joined, so you can reconstruct any color you liked by feeding its seed back in increment mode. That reproducibility is the whole upgrade.

Inputs and outputs

Required: seed, bits (16/32), mode (increment/random), count (1–100). Optional: random_min, random_max (only meaningful in random mode, and random_min must be less than random_max or it errors).

Outputs: hex_string and used_seed. With count > 1 both are comma-separated lists - a palette in one output, the recipe for it in the other.

Why V2 over V1

Three concrete wins. used_seed turns random mode from a black box into something you can log and replay. count makes it a one-shot palette generator instead of "wire up five copies of the node." And the input validation means bad ranges fail loudly ("random_min must be less than random_max") rather than silently producing garbage.

Where it sits in a workflow: pick a seed, generate 5–8 colors, dump the hex list into a prompt builder or an image-generation node that takes colors, and keep the used_seed string around as your reproducibility log. It plays well with the rest of the DJZ text/color suite and with any ComfyUI node that accepts hex color strings.

Gotchas

One quirk worth flagging: both outputs are typed INT/STRING in the schema, but with count > 1 they're comma-joined strings. If you wire used_seed straight into an INT input expecting a single number, a multi-count run can misbehave. Keep count at 1 when you want single-value outputs, or treat the outputs as strings once you batch. Also note the "bits" choice is about display width, not color depth - 32-bit just preserves more of the seed in the hex.
