You used black and cyan? Big ****ing deal, so did every other set that used those colors, perhaps not exclusively, but they were used before. Did you ask everyone that had a black alpha or modifier in previous sets for permission? I assume not, because that would be retarded.
I never said that I own such colorway, please read my response more carefully and also watch your mouth since I never spoke with you before and I'm being civil. In response to your question, I'd definitely ask other Signature Plastics' designers for permission to use such color way, if any ever existed.
You didn't "create" anything, you matched colors and people liked it. Pulse is a nice looking set, but it is not art nor any sort of legitimate intellectual property. Get over yourself. That type of self entitled behavior is childish and arrogant.
I'd like to inform you, in case you didn't read such information anywhere before, that I personally dislike the keyset, it's colorway and its novelties. In retrospect, from my personal opinion and design experience I can honestly say (and already said it before) that the set could have used better ideas and in the end doesn't look that good. Please point to me where I was arrogant in my previous reply. If I sounded like that I apologize but it was never my intention and I'm not a native speaker.
However, despite of what you think I did create the set, since I spent many hours digitally painting a virtual keyboard layout and importing patially done sketched by hand drawings, to be used as novelty icons in the vector form. And according to my interpretation of the English language dictionary (below) what I did and what I do can be categorized as art, even though the set itself isn't my direct manual craft, but Signature Plastics'.
art; (noun)
1 - The expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power;
2 - Works produced by human creative skill and imagination;
PuLSE was result of my creative skills and imagination.
Side note: your pulse icon looks like a QRS trace, did you ask for permission to use that? I doubt it, because no one ones the concept.
Such icon is a letter "M" meant to represent my nickname on this forum even though it resembles a QRS trace. It looks vibrant and full of energy, like myself, so I decided to name the set "PuLSE". The keyset was originally a personal print to be requested from WASD, but since others liked the idea I decided to develop it together with RMK and this community until it became a group buy. It's design went through many iterations, one of them featuring the Cherry Replica font which was discarded due to the steep price.
Second note: Tron (2010) made heavy use of black and cyan, did you ask Disney for permission? I doubt it, because that would be unreasonable.
Disney indeed used cyan and black in this beautiful movie, but again I never said that I own such color way or created it. I did however apply it to Signature Plastics' keycaps before anyone else. Below you can see highlighted exactly what I said on my reply:
The premise is that such colorway, applied on keycaps created and manufactured by Signature Plastics is a design concept that I created.
